This is an application I made in MaxMSP. It takes MIDI notes C1 - A1 and maps them to the corresponding MIDI channels for the sample slots 1 - 10 on the Korg Volca Sample. This enables users to easily trigger sounds via the device's MIDI input. The Volca Sample is setup so that each sound exists on a different MIDI channel so, for example, when you hook a keyboard straight to the device's MIDI input, you're only able to trigger one sample since the keyboard sends notes on only one channel. This application gets around that limitation. To use it, just push the buttons and then select where your MIDI source and destination from the dropdown menus. I hope that this works well and is helpful. Click on the little square picture to download.
