Bitwig Parsec-8 Modulator - Per Step Modulation Step Modulator
Bitwig Guide | Jul 26, 2022
Parsec-8 in Bitwig Studio is an 8-step bipolar sequencer modulator with individual step disabling, holds, and output handles for each step, offering flexible modulation and creative playback options, including phase offset, smoothing, speed control, and direction modes. Unique to Parsec-8, each step can be modulated independently, with playback synced to transport, free-running, or even driven by note or pitch inputs, enabling advanced rhythmic and sound design possibilities, from stepped LFOs to monophonic synths. The device supports intricate timing adjustments, groove integration, and real-time musical manipulation, making it a versatile tool for dynamic modulation and draw-your-own oscillator shapes.

Short Overview #
With the Parsec-8 modulator in Bitwig Studio, I can create dynamic modulations using up to eight configurable steps, each with its own bipolar value and individual hold or disable options. I can control playback direction, speed, and phase, and even sync everything to the transport, groove, or let it free-run. Smoothing lets me create fluid transitions, and having separate outputs for each step gives me a lot of routing flexibility. Whether I’m shaping audio-rate signals, building step-sequenced modulations, or even making a basic synthesizer, the hands-on control feels creative and immediate.
- Parsec-8 modulator in Bitwig Studio is an 8-step sequencer/modulator, different from the regular step modulator.
- Each step can be deactivated, which ignores the value but does not skip the step.
- Hold function sustains the previous step’s value, useful for creating sustained modulation shapes.
- Step values are bipolar (can be positive or negative), and you have individual modulator outs per step.
- Playhead indicator shows which step is currently active.
- Step range can be limited, shortening the sequence to fewer steps for creative patterns.
- Features phase modulation for playback offset, allowing precise control over the start position in the sequence.
- Smoothing feature interpolates between steps, avoiding abrupt changes and clicks in modulation.
- Multiple playback modes: forward, reverse, ping-pong, loop, and several transport sync/groove options.
- Free running mode plays independently of the transport, and note-based modes include restart, random restart, and note advance.
- Playback speed can be set in synced musical values, hertz, kilohertz (audio rate), with variable divisions and dotted/triplet timing.
- Pitch mode allows playback speed to be controlled with MIDI note input, enabling use as a basic monophonic synth.
- Parsec-8 can be configured as a drawable oscillator, useful for creative modulation and sound design.
- Modulation output can be shaped and integrated for different musical or sound design purposes within Bitwig Studio.
Introduction #
In this video, I dive deep into the Parsec-8 modulator in Bitwig Studio, explaining all the functions, controls, and how they differ from the typical Step Modulator. Parsec-8 is a unique step-based modulation source in Bitwig, which has several distinct and versatile features suited for a variety of creative workflows.
Parsec-8 Overview #
Parsec-8 is an eight-step sequencer or modulator. Unlike the more traditional Step Modulator, which allows up to 64 steps and outputs a single modulation signal per sequence, Parsec-8 is limited to eight steps. What makes it special is that each step comes with its own individual modulator output, allowing independent modulation routing from every step.
Step Control and Disabling #
You can disable any step, but note this doesn’t skip the step in the sequence. Instead, the step is played but its value is ignored. This distinction is important for musical phrasing and modulation design.
Hold Function Explained #
The 'hold' value for each step sustains the previous step’s value into the current step. For example, if you enable hold on step 2 and step 1 has a value of 1, step 2 will inherit and maintain that value, allowing you to create longer shapes or sustain specific modulation moments.
Working With Bipolar Values #
Each step’s value can be set independently and can be either positive or negative. This makes Parsec-8 a bipolar modulator, enabling a wide range of modulation from inverting to complex polarity-based patterns.
Individual Step Outputs #
What truly sets Parsec-8 apart from a standard Step Modulator is that each step provides its own modulation output. This means each of the eight steps can affect different parameters and devices independently, opening up intricate modulation possibilities.
Playback and Step Range Options #
An indicator highlights the currently playing step, giving you real-time visual feedback. You can also limit the range of the sequence, for example, making it play only the first two or three steps, effectively shortening the playback loop.
Comparison With Step Modulator #
Parsec-8 is capped at eight steps, whereas the Step Modulator can go up to 64. This makes Parsec-8 more focused but with a richer output per step.
Phase Modulation and Playback Offset #
Parsec-8 uses phase signals from the Bitwig transport system, a ramp signal going from zero to one across a bar, to synchronize or modulate step playback. Phase modulation lets you offset where you are in the sequence, effectively shifting playback position using other modulators. This provides dynamic positional changes tied to the transport or independent sources.
Smoothing for Transitions #
Smoothing is available to interpolate between step values, which reduces abrupt jumps between step modulations. When modulating sensitive parameters like gain or pitch, smoothing minimizes audio clicks and creates fluid transitions. Overdoing smoothing, however, can flatten out modulation entirely.
Playback Direction and Modes #
You can choose how the step sequencer moves through steps: forward, reverse, or ping-pong (bouncing back and forth). This flexibility supports a range of rhythmic and modulation effects.
Looping and Transport Synchronization #
Parsec-8 can be set to loop, stop at the end of a sequence, or synchronize strictly to transport controls. This means playback is always in sync with your timeline, starting and stopping in line with your project’s transport.
Groove Integration #
When set to 'Groove', Parsec-8’s playback will follow the global groove or shuffle settings in your project, making your modulations swing along with your beats and rhythms.
Free-Running Mode #
This mode detaches the sequence from the transport, running the step sequence independently at a chosen speed. Useful for LFO-style or un-synced effects.
Note-Driven Playback Modes #
- Note Restart: Sequence restarts at the first step with each note input, useful for per-note modulation.
- Note Random: Sequence jumps to a random step on each note input, creating unpredictability.
- Note Advance: Sequence advances one step per note, disabling regular speed controls for precise step-by-step modulation.
Playback Speed and Units #
Playback speed can be set in synced note values, Hertz (Hz), or Kilohertz (kHz, for audio-rate modulation). This covers slow, rhythm-based modulation all the way up to fast, audio-rate modulation for sound design. If the modulation is set in audio rates (for example, 1 kHz or above), you can use Parsec-8 as a drawable oscillator to generate waveforms, modulate sounds, or create custom LFOs.
Division and Dotted/Triplet Values #
You can dial speed between standard divisions like 8th or 16th notes, including dotted and triplet values for more complex rhythmic modulation. The speed knob allows fine divisions between these units for tight control over modulation timing.
Pitch Mode: MIDI-Driven Modulation Rates #
In pitch mode, the playback rate is modulated by MIDI note input. Higher or lower keys on your keyboard speed up or slow down the sequence steps, allowing you to 'play' the rate of modulation. With additional creative routing using devices like an ADSR envelope and DC Offset, you can create monophonic synthesizers or unique modulation-driven instruments.
Practical Sound Design With Parsec-8 #
By combining steps, output assignments, smoothing, and sync settings, Parsec-8 can serve not only as a creative modulation source but also as a drawable oscillator. For example, setting two steps at maximum and minimum values (like +1 and -1) yields a square wave at audio rates. Smoothing will morph this to a triangle or sine shape. You can even play this oscillator via MIDI using the pitch setting and trigger its envelope with ADSR and note events.
Conclusion #
Parsec-8 in Bitwig Studio is much more than an eight-step sequencer. Its design as a multi-output, bipolar, step-based modulator gives it immense flexibility for modulating parameters, creating rhythmic modulations, drawable oscillators, and even whole synthesizers. Exploring its many playback, synchronization, and smoothing settings lets you push modulation well beyond the basics, making it a powerful tool for advanced sound design and creative sequencing.

[00:00:00] Parsec-8 modulator in Bittic Studio is actually 8 step sequencer or modulator.
[00:00:07] And we have also a step modulator, which is a bit different or works a bit differently.
[00:00:13] But this video is about this one here, the Parsec-8.
[00:00:16] So we are limited to 8 steps.
[00:00:17] We can disable each of these steps.
[00:00:20] And this is not a skip.
[00:00:21] As you can see here, it still plays the steps, but it just actually ignores the values.
[00:00:27] So it's not a skip.
[00:00:30] Then we have a hold value here.
[00:00:33] This basically sustains the previous value of the steps.
[00:00:37] So when we dial in here, hold for this one, and we have your value of one, actually have
[00:00:42] also value of one on this step here, because we want to preserve the previous value of
[00:00:48] this step.
[00:00:49] Right.
[00:00:50] So you can just hold the current value.
[00:00:54] Then we can dial in your values for each step differently, positive and negative.
[00:00:59] So it's a bipolar modulator.
[00:01:01] And we have also modulator handle out for each step, which is the big difference to
[00:01:08] the steps modulator, where we have just one modulator out for all steps.
[00:01:15] Then we have here also an indicator where we are in the sequence.
[00:01:19] So you can see what step it's currently playing.
[00:01:22] And then we have here down there, we have also some playback options.
[00:01:26] We can limit here the steps to maybe two steps.
[00:01:29] You can see also it shortens basically the playback range here, so it doesn't play all
[00:01:35] the other steps.
[00:01:36] It's only iterating over these first three steps here.
[00:01:41] So you can limit the steps and we have also maximum step size of eight.
[00:01:45] Steps mod has, for instance, a step max limit of 64, I'm not wrong.
[00:01:54] Then we have here the phase modulation, which is basically kind of a playback offset.
[00:01:59] So when we hit stop here on the transport, you can see we stop here at six.
[00:02:05] And when you dial in your phase modulation, you can see it's moving to the right.
[00:02:10] So we can offset the current playback position with this.
[00:02:15] It's called phase modulation because it's using a phase signal coming from the transport.
[00:02:20] Transport is sending out the phase signal, which kind of looks like a ramp signal going
[00:02:24] from zero to plus one.
[00:02:27] And this is used in Bitwig, of course, to position things.
[00:02:31] So with this phase modulation, you can offset the phase value and offset the playback to
[00:02:38] current playback position.
[00:02:41] If you switch this here to hold, for instance, you go back to the first step and then the
[00:02:47] phase modulation decides where you are in the playback.
[00:02:51] So you can modulate this here with a different modulator and change the playback speed or
[00:02:56] direction at any point in any kind of direction or way you could imagine.
[00:03:03] So back to bar here, maybe, or maybe eight notes.
[00:03:09] So yeah, we have here a limit.
[00:03:10] We have the phase modulation, we have the smoothing option here.
[00:03:15] So this is where you can interpolate between values.
[00:03:19] So we have maybe here a value of one and here we have a value of minus one.
[00:03:23] And this changes pretty drastic, right?
[00:03:25] It changes from plus one to minus one instantaneously.
[00:03:29] But when you modulate something, maybe a loudness or a gain knob or something like this, it produces
[00:03:34] clicks because you change the modulation so drastically.
[00:03:39] So you can dial in here smoothing and Bitwig tries to interpolate between these values
[00:03:45] and make the transition kind of smoother.
[00:03:48] I can show you this in a minute how it looks like in Bitwig here.
[00:03:51] So when we have maybe, let's say we modulate or we use two steps here and we modulate here
[00:04:00] this one.
[00:04:04] This one.
[00:04:05] You can see it switches between these two pretty drastically, right?
[00:04:11] When I dial in here smoothing, you can see it becomes kind of a nice modulation.
[00:04:18] If you do it too much, it doesn't actually move at all.
[00:04:28] So it's a smoothing option.
[00:04:34] Then back to this menu here.
[00:04:38] Then we have the playback speed so we can change here in which direction we want to actually
[00:04:41] play the sequencer.
[00:04:42] So you can see now it's in forward mode, now reversed and then we have also ping-pong here
[00:04:49] which alternates between forward and backwards or reverse, goes back and forth, right?
[00:04:55] So we have this.
[00:04:56] We have a looping function so it stops when we don't disable this.
[00:05:00] It actually stops after one iteration.
[00:05:04] Then we have transport here and these are some playback options.
[00:05:08] For instance transport basically synchronizes the playback of this Palsik A2 to transport.
[00:05:14] So when we hit stop here, it actually stops to play back.
[00:05:18] If we hit start, then it plays back from the start.
[00:05:22] It's also synchronizing to the position of where you are in your transport here.
[00:05:31] I think you can see every time I start from this position, it starts actually in the middle.
[00:05:40] So it not only synchronizes its starting point, it's also synchronizing when it starts to
[00:05:46] the transport.
[00:05:47] So this is why it calls the option of course transport.
[00:05:51] Then we have with groove which is the same as before as transport.
[00:05:55] But now it actually uses also the global groove option.
[00:06:01] So when you dial in some shuffle for all your beats and stuff like this, the modulation
[00:06:06] also uses that to bring in some swing into the playback here of the Palsik A2.
[00:06:14] Then we have free running.
[00:06:15] So the playback doesn't care for anything.
[00:06:18] It just plays back the sequence here over and over again without caring for anything.
[00:06:25] So it's just free running.
[00:06:27] Of course you can use the speed knob on the speed divisions or units and dial in a different
[00:06:33] speed for the playback start and where it started doesn't care at all.
[00:06:39] Then we have note restart.
[00:06:41] So you can see it just plays back here the sequence, but every time I press a key on
[00:06:46] my keyboard or input the note with the note clip here, it restarts and goes back to the
[00:06:53] first bar or to the first step.
[00:06:57] So you can restart with the note input to the first step.
[00:07:02] And then we have note random which does basically the same, but this time every time you press
[00:07:06] a key, it should restart at a different point.
[00:07:14] It's not really random, but every time you press a key it restarts and brings the playback
[00:07:22] indicator to a random point in the sequence.
[00:07:25] Then we have note advance which completely brings this sequencer to hold.
[00:07:30] And every time you press a key, you advance to the next step.
[00:07:36] You can also see here the playback speed is completely disabled, you can't use it.
[00:07:42] Then we have here the speed settings and we have here a dial so we can just dial in any
[00:07:50] setting in between synchronized steps.
[00:07:53] We can also use your hertz, we have playback speed here of one hertz.
[00:07:59] If you dial this down, then it slows down.
[00:08:02] If you speed this up, then playback speed is higher.
[00:08:06] And also kilohertz here, which is audio rate, so you can use this to create some sounds.
[00:08:11] So for instance, let's use here only two steps and we modulate here maybe this.
[00:08:19] And also this, and then we go to minus one, so this should be some kind of square wave.
[00:08:27] We can change here the, we can make music or sounds with this.
[00:08:40] And again, as before, we can use it as smoothing to make it this kind of an, let's use an oscilloscope
[00:08:46] here.
[00:08:50] So you can see we have your square wave, you bring in the smoothing, or this one here.
[00:09:08] We can make this kind of rounded, or we actually can use your three steps maybe like this.
[00:09:23] Let's see how this looks like.
[00:09:35] So you can go to audio range with this here.
[00:09:37] Then we have bar, which is super slow.
[00:09:39] It's actually one, you iterate through one of these eight bars here, you have exactly
[00:09:44] past one bar in your sequence or in your arranger when you dialed in one.
[00:09:50] And yeah, as I said, you can divide this here.
[00:09:53] So let's say you have eight notes here, right?
[00:09:58] And you hit play.
[00:09:59] So each step is basically eight notes.
[00:10:04] And if you dial in here 0.5, it's actually twice as fast.
[00:10:08] So it's 16th notes, even though you are selected to eight notes.
[00:10:13] So it's probably faster to leave this at one and then switch it to 16th notes, which has
[00:10:19] the same effect basically, but you can dial in here some values in between.
[00:10:25] If you want to have some, some speed setting between eight notes and 16th notes, and you
[00:10:30] can divide this here with the snob, right?
[00:10:32] So you can also go to my 2.0.25, for instance, something like this, right?
[00:10:40] So you can also dial in some dotted things, but you probably want to use here these different
[00:10:46] units for dotted 16th notes, 32nd notes, and so on, triplets also.
[00:10:51] So you can dial this in here, and then you use the speed knob to divide it even further
[00:10:56] if you want to.
[00:10:57] Then we have down here below everything we have pitched to off-current note.
[00:11:05] So this is interesting.
[00:11:06] It's kind of using kilohertz that goes into audible ranges, but here you actually can
[00:11:13] use the MIDI input or the note input of your MIDI keyboard or your note clip to change the
[00:11:19] playback speed.
[00:11:21] So if we put this here to pitch, I can play on my keyboard, on my MIDI keyboard and can
[00:11:27] change the playback rate here.
[00:11:40] So you can do kind of a synthesizer with a DC offset device, which is more or less there
[00:11:47] to remove DC offset.
[00:11:50] But you can also use to make it like an instrument, right?
[00:11:54] So all we need to do now to actually make this a synthesizer, a monophonic synthesizer,
[00:11:58] is using here an envelope, ADSR.
[00:12:01] You can also describe that thing in some video before.
[00:12:06] And every time we press a key on the keyboard here, we can see we have here the ADSR reacting
[00:12:11] to it.
[00:12:12] We use this to change actually the volume or the amount knob here of the Palsik 8.
[00:12:20] So every time we press a key, we dial in or we bring in the amount, and we also change
[00:12:27] the pitch to the current key of the MIDI keyboard.
[00:12:34] It's a perfectly nice, small, little, monophonic synthesizer you can do with the Palsik 8 here.
[00:12:41] And also the oscillator itself, it's a drawable oscillator if you want to.
[00:12:48] Okay, so I described you all these knobs here, how this works, what it does, and you find
[00:12:55] more tips and tricks on some practical examples on my main channel where it's all about making
[00:13:01] music instead of describing what the manual says.
[00:13:06] So this is only to describe basically what each knob does and how you kind of use all
[00:13:13] these settings here.
