Moonsound Music Editor and Replayer Using only Samples

Cubase-style (like many DAWs) and trackers are totally different paradigms. The only non-tracking thing that comes close would be a score editor. Of course, you can just drop your notes in a pianoroll editor, but then it's time to compare navigation and functionality. Here a good tracker wins, big time. The only thing you could say is that MBWave and MBFM are heavily dated, and were in fact already dated when they came out, and were certainly limited compared to what the OPL4 can do. It was a quick hack because the Moonsound needed something, so the old Moonblaster was given a paintjob, and not much more than that.
Your pianoroll with notes and velocity bar is slow. You might like it, but when I'd be entering the same notes in a (good) tracker, I'd be halfway the next game already when you're done finishing one song. For the same reason, it's faster to type/add values in an Excel sheet rather than having a graphical representation where you need to mouse around and use graphical methods/conventions to add data.
Having said that, and let me emphasize that you may certainly like a piano roll editor, it'd be even better whether there'd be a Moonsound VST with full access to samples and FM. Then anyone can use any editor you want, be it a piano roll or a VST-tracker. I might even propagate that openMSX should also become a VST, then from any DAW you can have access to all PSG, FM, SCC, OPL4 sounds you'd want. ^_^

A while ago I was fooling around with Deflemask. It's a tracker with which you can input notes through your connected midi keyboard, be it after you put the cursor there where you want it, but it's nice.
Played a bit with a pianoroll tool a while ago as well. Must've been a very bad one because I can not see how anyone could prever that above a good tracker. One big mess on the screen as soon as I added more parts.

One request could be to import MBWAVE/MBFM data. That way you can have musicians work for you even if they're not comfortable with piano roll.

So, I have been working more on this, and in the end I am using the moonsound cartridge to play back midi files.
In any Digital Audio Workstation/DAW (I'm using Cubase 10) I create a track in midi.
I do however assign my own .wav file samples to the midi tracks.
These .wav files I then load into the moonsound cartridge, and my replayer then plays back the songs on the msx.

So far it's working pretty good, and the replayer is very fast. (5 screenlines at max per frame)

Next thing I wanna do is utilise also the 512 sounds which are already present in the moonsound cartridge.
Is there a list of all these sounds ? Because eventually I would like to have samples of all those files,
so that I can use them in a DAW as well.

I listened to the first 8 sounds:
0= sine wave
1= blender, chopper wtf
2= synth sound
3= sound of a fax machine
4= piano
5= piano/ac guitar
6= keyboard trumpet sound
7= keyboard trumpet sound
8= ocean water / sand sound

Thanx, I got it !!

It seems now that im trying to use the sounds that every instrument is in a different pitch.
If I take my song, and put a piano sound on channel 1, a guitar sound on channel 2 and a banjo sound on channel 3,
the whole song is out of tune....

Why didn't they sample all the sounds on one fixed frequency ?

Now I have to adjust the frequencies per sample in my replayer ??? Am I seeing this correct ?

@grauw
Another thing I notice is that in the list of the linux driver you just gave me I see these instruments:
00[] = { /* Acoustic Grand Piano */
01[] = { /* Bright Acoustic Piano */
02[] = { /* Electric Grand Piano */
03[] = { /* Honky-Tonk Piano */

while my list of sounds that I tried are completely different:
;000= sine wave
;001= blender, chopper wtf
;002= synth sound
;003= sound of a fax machine
