HOW-TO: BeatStep Pro Drum Sequencer with KORG Electribe 2

[Steinberger]

Posted today on Arturia Forums for those interested.

Supports both Electribe 2 (8 parts) and Volca Beats (all instruments) on same Drum Sequencer and channel with a little overlap being two of the pads trigger two instruments on both machines. Not a bad thing. You'll see.

Geez what a bear (no thanks to Arturia) but it works great.

Excellent work.

Thanks a bunch!

A youtube demo of this would be great!

Unfortunately, I'm not on the YouTwittFace :/

If someone wants to give it a go and post a vid or improve it that would be nice. Also note there's a post in the Volca forum just today of @mmaisterrena dong this to a Volca Sample using an Arduino board.

Hi there,

FWIW, I've managed to adapt @mmaisterrena Arduino solution to use the BSP Drum sequencer with the electribe 2 range, restrained to the 8 bottom pads of both units (as per the default e2 patterns posted here).

Works like a charm, and just slightly messes up the BSP MIDI clock by a 0.2% margin. The BSP clock being ~3.2% jittery according to my MidiGAL, let's assume it's barely noticeable.
I'll try to use interrupts later anyways.

Since I've had little success with the Arduino MIDI Library, the code that works is a trimmed down and customized version of MIDI Channel Filter by Tom Scarff.

It also filters useless aftertouch messages sent by the BSP on channel 10.

If anyone is interested, I'll be glad to post the code here (once cleaned up a bit).

Cheers.

For the sake of simplicity, looks like someone has made an intelligent self powered MIDI device doing this MIDI note<->channel conversion for the Volca Sample:

It can do a lot more, configuration being generated into a web browser with jazz-soft plugin.

Pretty neat, I'd say.

very interesting!!
you have to understand if you can use a rk002 to connect Electribe Sampler 2 - slave (16 MIDI channels for 16 pads) to a Beatstep pro - master (single "midi channel 10" for all 16 pads)?

Just wanted to drop here that with the latest BSP firmware upgrade (2.0) you can now set each drum instrument in the drum sequencer to a different MIDI channel. It now works great with E2/S and Volca Sample. I have my Electribe trigger set to none so I can use the pads in trigger mode to just select an instrument quickly. No extra equipment necessary and it all still fits into a laptop bag.
