I don't think so, there must be some provisions in the DMA-channels
(Agnus) that allows to retrieve more data for additional channels.

The C64 multi-SID devices had their disadvantages. It was 'MUCH' noise
introduced into the audio signal.

I'd say, a cheap MIDI extender plus some software to use the internal
channels as a virtual MIDI device should be the better solution.
