Ms-20mini + EWI (breath controller)

Post by tito_tunes » Sun Mar 08, 2015 11:20 pm

Just got my MS-20mini today and I'm in love! I first learned synthesis on my friend's original MS-20, so it's a familiar interface for me. I got a steal of a deal on the mini at $350 off of Craigslist. I bought it specifically to use as a sound module for the EWI4000s.

Here's a sampling of my experiments today:

At first I thought I might get away with using the External Signal Processor to convert the EWI's audio into pitch and breath amplitude CV. It works ok... but the tracking is weird beyond one octave, and it seems like the breath dynamics contaminate the pitch CV.

Fortunately I have a Waldorf Pulse + which can function as a MIDI to CV converter. That gave me better results. Now I can play the MS-20mini using the EWI's pitch bender and bite sensor, all tracking beautifully. I found I got the best results with pitch CV going into the OSC 1,2 input and the breath CV mapped to VCF and VCA. No gate trigger necessary! Patching it in only made it sound clicky.

One drawback I encountered with using the Pulse as a MIDI to CV converter is it doesn't include portamento in the pitch CV. One of the awesome features of the EWI is the thumb sensor for controlling portamento time, to create all sorts of slippery leads and bass. I think I might at some point pick up a Kenton MIDI to CV box, which I think will pack the pitch bend and portamento time (cc#5) in with the pitch CV.

Nice work! I use a Yamaha bc1 in most of my arrangements (Brass/Woodwinds) so this really appeals to me. BC sure brings everything it touches to life!

Again, well done!
