KRM Electronics MIDI-CV Converter Prototype Demo

Published on Nov 25, 2013 krmelectronics·10 videos

"This is a demo of my performace-oriented MIDI-CV converter. The unit shown is only a prototype. I'm planning on making a module based version, and also a small PCB suitable for retrofitting a mono-synth.

In the demo I'm using an Ensoniq SQ1 as a MIDI controller. It's not producing any sound. All of the sound comes from a Paia 9700 modular. I'm also using an Akai LPD8 to send MIDI button presses, and continuous controller messages.

My MIDI-CV converter takes the merged MIDI stream, and outputs 2 CVs and a gate to the Paia 9700.

All of the arpeggiator functions can be controlled in real time via MIDI:
- MIDI sync On/Off
- MIDI clock ratio (from whole notes, all the way to 32nd triplets)
- Speed (when not synced to MIDI)
- Gate time
- Latch On/Off
- Arpeggiator pattern (Up, Down, Up-Down, Down-Up, Repeat End Note, Random, User Defined)
- Arpeggiator octave span (1 to 5)"

Note: I created a KRM Electronics label with this post. I added the label to the other technical overview and repair videos by krmelectronics as well. Labels typically get created for new makers & manufacturers and may be applied to posts not featuring their products to give you more insight into their interests and background.

Site Tip: See the manufacturer channels at the bottom of posts for more. You can find the channel label drop down on the right of the site. Or if you know the channel you can click on any channel in a post and replace the channel with the one you want, for example: http://www.matrixsynth.com/search/label/KRM%20Electronics to http://www.matrixsynth.com/search/label/Moog.

Bach Two-Part Invention No. 1 - EMS Synthi - Moog Source

Uploaded on Jan 20, 2012 krmelectronics·10 videos

"Bach Two-Part Invention No. 1, played on an EMS Synthi and Moog Source. The audio was recorded directly to 1/4" tape (Revox PR99 at 15 IPS) and dubbed back into the video. The Synthi was played via a Yamaha MIDI controller, and a Paia 9700 MIDI-CV converter. The reverb is from an Alesis Midiverb II.

Since the Synthi expects 0.32 v/oct, but the Paia MIDI-CV converter output is 1 v/oct, I had to run the output of the Paia through a simple voltage divider circuit (not shown in the video) to convert it."

Interfacing 1 v/octave Equipment to the EMS Synthi

Published on May 16, 2012

"This video describes how to use a voltage divider circuit to interface the EMS Synthi to 1 v/octave equipment (like Moog, Roland, or other synthesizers). The EMS Synthi uses 0.32 v/octave, but almost all other synthesizer manufacturers use 1 v/octave."
