Guru is a Renoise tool for editing sounds on external hardware synths via MIDI. It provides a generic user interface for editing the parameters of the synth, and let's you store them as patches, that can be restored later on.
Guru also saves the patches with the song, so when you re-open a song synths and the patches you were working with when you saved it are restored.
All the parameters are MIDI assignable, so you can use it to map any MIDI controller to the synth.
