Momo has created useful MIDI editors for Korg volca Bass, volca Beats, Roland AIRA TR-8 and TB-03 and the JU-06 too. His latest release is a new MIDI Editor (standalone and VST) for the Roland TR-8S drum machine. The editor comes as both a VST and Standalone for PC 32/64 Bit and Mac as VST, AU and Standalone. The TR-8S parameters can be automated, and they can be stored in your song. With the X-Y-Pad all controls can be selected and controlled. This makes it useful for designing sounds.
