Thanks again :]

And for those who may be concerned about this, for my needs MIDI tracker, projectMIDI and and Euterpe look promising, too (I downloaded all from Aminet). I'll give it a try. Of course I'll write some feedback then.

I'm surprised you had problems with OctaMED, I've used it for MIDI sequencing for years.

Ensure that MIDI is enabled in the midi menu, then go to the instrument editor.

Pick a midi channel and set the transpose to around 36 (that's what I have to do for most GM patches), volume to 40 (hex) and set a non zero preset. Play a few notes, you should hear something at least.

@Karlos and The Goose:

How do I pick a MIDI Channel in instrument editor? Or are you guys talking about that option that's under MIDI?

Where do I set the Transpose settings?

What is a GM patch?

What's non zero preset?

Thankx!


You need to use the Instrument Properties window (see attached image).

In this window, you will find sliders for the midi channel, volume and transpose. You need to at least set the midi channel to something from 1-16.

You will also need to set the volume slider as this controls the default "note velocity" for MIDI instruments.

You may need to set the transpose too. As I said, 36 seems to be the norm for most patches I use. I also use 24 for bass patches.

A patch is just MIDI parlance for an instrument. GM (General MIDI) defines 128 basic patch numbers that are grouped into related sets. Most MIDI gear also allows banks to be selected, such that for each GM patch there may be several variations according to the selected bank.

If you don't set the MIDI preset in the Instrument Properties window, whatever MIDI patch is currently assigned to that MIDI channel will play on the target MIDI device.

Depending on how your MIDI device handles instrument variations, you can tick the "Extended Preset" checkbox and the range of available patch numbers in the preset slider becomes much larger. My hardware tends to use bank select messages for that, so this option doesn't work for me. Your mileage may vary.
