ISR seems to be at 0x2CFC
and indeed, it seems to get written around there
oh, it deopends on #3FF6 and #3FF5, which are the MIDI DATA and STATUS registers, which are not properly implemented

Do you have the disassembly for the ISR at 0x2CFC where it updates F9A2?

This is the ISR (it's the routine that is jumped to at 0x38), actually, the first 200 lines, I didn't check where it is actually ending:

Does anyone have some tips to configurate BlueMSX for DMS1 and for DMS2? I forgot everything.......two years ago I have a configuration, I´m shure for DMS1, but it won´t work today Question

DMS2 needs a CX5MII (or any MSX(2) with memory mapper I guess) and the SFG-05 sound module.

Also there’s this page: http://www.msxblue.com/manual/cx5m_c.htm

On the Resource page of the blueMSX website, you can find many Yamaha machines that include the SFG-05 module and have mapped RAM :

CX5MII / CX5MII-128 / CX5MII-2 Uwe Neisius / CX7-128 / CX7M-128 / YIS604 / YIS604-128 / YIS805-128 / YIS805-256 / YIS805-256-2+

At the moment, DMS Mark 2 does not work on emulators (additional support for MIDI part is required).

And DMS1 only works with the SFG-01 in slot 3. So a standard Yamaha CX5M configuration is a good example.

blueMSX comes with 2 CX5M machines (CX5M-1 and CX5M-2) and 2 CX5F machines (CX5F-1 and CX5F-2, only on the Resource page).

Version 1 is with SFG-01 (use the improved config on the Resource page), version 2 is with SFG-05.

OK, Thanks. CX5M with DMS1 seems to work.
One question: Do I have a CX5MII in 1986? With a SFG05?
I forgot it totally, the only thing I know is, Ive got a Sony Floppy Disk and the DSM-1 and it works perfect.
Or do I have the first CX5M with SFG01?

we are searching pictures to solve this riddle......
