Sending at 3 kB/s is no problem for me either - that's the speed used by amidi (and other apps using the rawmidi interface), actually. The method used for transferring sysex data in DOSBox, however, sends at almost 13 kB/s, which is too fast. I haven't tried the Windows version yet, as I'm almost …

Status report: I've created a simple version of amidi that uses the event interface to send sysex commands. As a reference, I used pmidi and the alsa-lib sources, so the code should be using ALSA correctly (but my work was sloppy, so I can't be sure :-)). Basically, what my program does is this (my …

Will do. The next step will require a little more time, though, as I didn't have any experience with ALSA's sequencer interface before yesterday. I'll have to study the API carefully and do some experimentation on my own before I can get any further.

Apparently, some SysEx messages get through. I tried disabling SysEx completely by commenting out snd_seq_ev_set_sysex(&ev, len, sysex); send_event(1); in src/gui/midi_alsa.h's PlaySysex() function, and the resulting sound was different from when the lines were enabled. I know snd_seq_ev_set_sysex() …

I have a plain CM-32L, so there should be no problems. I did some reading in the code, and saw that DOSBox uses a different method to send SysEx commands. Unlike amidi, which sends sysex commands directly to the raw device, DOSBox uses snd_seq_ev_set_sysex() followed by send_event(). Could I be …

I did a quick strace on DOSBox while it was starting QFG2, and it didn't even open the raw MIDI port (/dev/snd/midiC0D0 in my case), which is where amidi sends SysEx commands. Does this mean that all SysEx commands are discarded, and it's just a coincidence that other games I've tried sounded OK?

I recently discovered the wonderful DOSBox emulator, and soon learned that it could make use of my old Roland CM-32L module. I hooked it up a few hours ago, and it seems to work great with every game I've tried, except for some (perhaps all) of Sierra's 16-color SCI games. For example, in Quest for …

Sorry, that was not exactly correct. The number of preset timbres in the LAPC-1's rythym section is 30 , not 34 (four of them appeared twice), which is exactly the same as the MT-32. The LAPC-1 and the CM-32L both have the extra 33 sound effects that the MT-32 does not have, though. Having found no …

Okay, I did some more searching on the web and apparently, the LAPC-1 has 128 sound patches, 34 drums and percussion sounds, and 33 sound effects. Does anyone have the numbers for the CM-32L?

I recently found out that, contrary to what I have always believed, the LAPC-1 is not a repackaged MT-32, but actually closer to a CM-32L. From what I hear, the CM-32L was released after the MT-32, and was improved somewhat (more RAM or ROM, extra sounds). Most of the information I've found on the …
