Ability to map more than 4 external hardware with midi out i

I got more than 4 hardware synths :
- DX7
- BK7m module (multitimbral)
- Juno Gi (multitimbral too)
- Minibrute
- Bass station 2
- SH-201

Some of them are linked with USB, some of them are going in the Midi ports of the MPC. Anyways they're all connected. But everytime i open a new project, i need to choose 4 of them to be mapped.

While i not use all of them at once in a singe track, i'd find it convenient if i could map in the software 16 midi out (or more) instead of only 4.

I don't think this would be too hard to implement in a future update.
