Each sequencer channel has its own record panel. You can use the step recorder to input a sequence into a channel from the instrument's own mouse keyboard, from the computer QWERTY keyboard, or from an external MIDI keyboard (the channel must be configured to receive the note input, via the setup panel).

In combination with the pattern matrix modulations and bar sequencer, the record panel permits algorithmic music composition. Husserl offers a unique multistep-record mode with real-time play that can mix any number of incoming sources (whether they be MIDI, other Reaktor instruments, or other sequences playing in Husserl) with simultaneous playback. Each incoming note is recorded as a new step in the pattern (up to 16 steps). At the end of the pattern, the recorder timepoint loops and records over the prior steps.

While recording, any channel can playback in step, loop, layer, and fugue modes. The playbacks can also modulate each other.

Uniquely, Husserl can playback a pattern live in a different tempo, while it is still recording, and simultaneously modulate another channel (even one from which it is recording), and also any such live channel can be recorded on another channel which is also in live playback. Thus, multiple recording channels can record, playback and modulate each other, creating dynamic patterns which continually evolve and change in unique ways.


Enables record for the channel. When the record mode is turned off, all the panel controls except the ON button are hidden from view.

On activation, the record point resets to the first step, then starts step recording. Each incoming note advances the record point by one step. Notes are recorded as they are received (prior to any modulation).

If no triggers are selected in the modulation matrix, the channel records from MIDI. Otherwise, it records from selected channels.

2. FWD, BACK (Record)

Manual triggers to move forward and back one step, intended for MIDI step recording. FWD lets you skip notes, if you want to leave a previously recorded note, or leave a step space. BACK lets you re-record notes, if you want to replace some notes you just keyed in. When the pattern step reaches the beginning or the end of the range, it wraps. If the pattern direction is staggered, shuffled, or reversed, the FWD and BACK motion correspondingly skip steps and reverse.

3. Version Notes

In v098 and later, transpose and channel gain settings in the pattern panel are applied to the recorded notes and stored in the pattern, rather than applied to the output.
