The Config menu gives you access to 4 standard configurations that help match the messages sent by Osmose with what is supported by your external synthesizers.

Selecting a MIDI configuration will adapt the messages sent on Osmose’s USB MIDI Port 1 and on its DIN MIDI output, also see connect Osmose to your computer. These configurations also contain a dedicated sensitivity setting optimized for the use case. 

 

ℹ External MIDI configurations can be fine-tuned via the adjust and sensitivity menus.

 

ℹ Your last configuration will be kept when turning Osmose off.

 

🚧 saving your own external MIDI configurations will be possible with an upcoming firmware update.

 

Turn Value Encoder 4 or use the Preset buttons to step through the following MIDI configurations:

mpe

is the default for controlling MPE-compatible software and hardware. 

It sends MIDI messages according to the MIDI Polyphonic Expression standard. 

The Pressure axis sends Velocity (MPE Strike) and Channel Pressure (MPE Pressure).
The Aftertouch sends CC74 (MPE Timbre, also called MPE Slide because it's the parameter that other MPE controllers often address with a sliding movement along the Y axis on the playing surface).
Note Bending sends pitch-bend messages (MPE Glide). MIDI channel 1 is reserved for global messages, and channels 2 to 16 are used to transmit one voice each. 

classic keyboard

is the best choice for full backward compatibility.

It sends MIDI messages like a legacy MIDI keyboard would do. The ‘Note On’ threshold in sensitivity menu is moved down further along the key travel to mimic traditional keyboard actions.

The Pressure axis only sends Velocity, and the Aftertouch axis sends Channel Pressure, commonly called (mono) aftertouch. Note Bending is deactivated.

All messages are sent on MIDI channel 1. 

poly aftertouch

is perfect for controlling software and hardware synths that offer polyphonic aftertouch.

It behaves just like the Classic Keyboard configuration but sends Polyphonic Aftertouch instead of Channel Pressure for the Aftertouch axis.

multi-channel

is useful for imitating the advantages of MPE with non-compatible software and hardware. For this, multiple instances of the same plugin or sound should be dialed up in the external device, each responding to a single MIDI channel. 

The Multi-Channel configuration behaves just like the MPE configuration, where one MIDI channel is used to transmit one voice each, but lacks a channel for global messages. To compensate for the lack of a global channel, global messages like CC1 (modulation slider) are sent as copies on every active channel.
