teoperator lets you easily make drum and synth patches for the op-1 or op-z. You don't need this software to use teoperator - you can use most of the functionality via teoperator.com. You can also use this software via a command-line program that gives you more functionality - to create a variety of patches from any number of music files (wav, aif, mp3, flac all supported). I did a write-up of how it works, basically I had to reverse engineer pieces of the metadata in the op-1 and op-z patches.

teoperator requires ffmpeg. First, install ffmpeg.

To use as a command line program you first need to install Go and then in a terminal run:

go get -v github.com/schollz/teoperator@latest

That will install teoperator on your system.

You can use teoperator to create drum patches or sample-based synth patches for the op-1 or op-z. The resulting file is a .aif converted to mono 44.1khz with metadata representing key-assignment information for the op-1 or op-z. You can use any kind of input music file (wav, aif, mp3, flac, etc.).

To make a synth patch just type:

teoperator synth piano.wav

Optionally, you can include the base frequency information which can be used on the op-1/opz to convert to the right pitch:

teoperator synth --freq 220 piano.wav

To make a drumkit patch you can convert multiple files and splice points will be set at the boundaries of each individual file:

teoperator drum kick.wav snare.wav openhat.wav closedhat.wav

To make a sample patch you can convert one sample and splice points will be automatically determined by transients:

teoperator drum vocals.wav

To make a drum loop patch you can convert one sample and define splice points to be equally spaced along the sample:

teoperator drum --slices 16 drumloop.wav

The webserver requires a few more dependencies. You can install them via apt:

$ sudo apt install imagemagick 
$ sudo add-apt-repository ppa:chris-needham/ppa
$ sudo apt-get update
$ sudo apt-get install audiowaveform
$ sudo -H python3 -m pip install youtube-dl

And then you can run the server via

$ git clone https://github.com/schollz/teoperator
$ cd teoperator && go build -v
$ teoperator server

Then open a browser to localhost:8053!
