A new sequencer

I haven't mentioned it on this blog yet: I bought a second-hand Beatstep Pro from Arturia.

Beatstep Pro


Beatstep Pro is a triple sequencer: two melody sequencers and a dedicated drum sequencer.
It has MIDI and USB inputs and outputs, but above all CV/gate/modulation and trigger outputs, which are useful for driving a modular synthesiser.
My now-ancient Korg SQ-1 pales in comparison. The Beatstep Pro can be used as the master sequencer in my setup.

This machine is cool, very playable and goes perfectly with a modular synth. Not much else to say about it.

Synth setup

Here's an illustration of a song in which the 4 tracks are controlled by the Beatstep Pro and generated (in part) by the synthesiser in a single take.



Drums and percussions : Korg Volca Sample (808 samples) MIDI-driven by the Beatstep Pro and two synth-generated percussions (Pony VCO+noise -> Multimode filter -> Percall). One of the sound is treated with Beads.
Bass : Doepfer VCO (PWM) -> Ripples 12db/oct How Pass Filter -> VCA (enveloppe from Rampage) -> Twin Drive
Melodies : Rings (polyphonic mode -> Left output in a reverb / Right output in a delay.  In polyphonic mode, when both Rings outputs are used, one trigger triggers one output, next trigger triggers the other one. Two melodies in one.
FX unit : Line 6 HX Stomp
DAW : Reaper with EQ and compressors added
