This emulator is based on reverse engineering work done by Paul Schreiber of SynthTech. If you are into synthesizers and electronics, it's a must watch!

So far this is only a standalone C program that processes .WAV files, but in future it will be adapted into plugins/VCVRack module/Raspberry Pi Pico device.

So far it's emulated:

• the core DSP engine
• output saturation

What's missing:

• input pre-emphasis and filtering

Requires libsndfile to build.

apt-get install libsndfile-dev

Then just make.

Inputs and outputs are stereo WAV files, 22 KHz, 16-bit, signed integer.

The output is 100% wet.

$ sox i_feel_so_liberated.wav -t wav -e signed-integer -b 16 -r 22050 input.wav
$ ./midiverb midiverb.rom 21 input.wav output.wav
channels=2, sample_rate=22050, num=198636

The programs are indexed from 1 in the same way as they are on the original unit.

TODO: Create a table with list of programs

The effect ROM is not distributed with this program and you have to obtain it yourself. If you own a MIDIVERB/MIDIFEX unit and don't want to dump the EEPROM yourself, you might look for a synthesizer rom archive.

This program was tested with the following roms
