I have a Zoom RhythmTrak RT-123 drum machine. It only has a MIDI in, and I want to have my sequencer (Cubase SL) trigger certain sounds on the Zoom.

My problem is, the sounds I want are not in the GM drum map. I am having a very difficult time figuring this out. I have the Zoom manual which maps the sounds, but the numbers don't seem to match up with the options I have in Cubase.

For example, in Cubase I have options like I-Note, O-Note, and channel. On the zoom, I have info like Note, Pad and Kit number.

Can anyone give me the secret code to unlock this? This seems to be my biggest MIDI issue - mappings sounds.

In the back of the manual is a reference section showing the different kits sound and various numbers. Page 66 actually shows what note numbers will trigger which sounds for the drum kits. Obviously not each kit has the same sounds but from this you can get the idea of which note number to us to trigger the particular sound.

So what you need to do in Cubase is make sure that you are sending out the right midi note number to trigger the correct sound.

My guess is that you will only have access to the sounds for the particular drum kit that is loaded. I did not see a section where you could create your own drum kit, so unless you can customize the existing kits, you will be stuck with the sounds from one kit at a time. If you were really desparate, you could use the program change to change from one kit to another.

Thanks, but maybe you can give me more info?


Thanks for your reply. I looked in the back of the manual before my inital post. I do see the program numbers, but they don't make any sense in relation to what Cubase is asking for.

I assumed that O-Node on the Cubase MIDI track (the Output Note) would be where I would put the MIDI note number. For example, the default for the kick drum in Cubase is C2. When I play it, I get the default kick drum. If I change that value, I get other sounds.

However, when I put the midi note number that is listed in the manual, I do not get the correct sound. First, it converts the numeric value I enter into a letter/number combination, and the sound produced is not correct.

I cannot see any relation between the midi note numbers listed in the manual and what Cubase is asking for. I guess this is a more fundamental problem with myu understanding or midi.

If you can help me break this secret code, I would really appreciate it.

The conversion of the midi note number to a letter number combination is probably cubase converting it to the corresponding note. The note would be one of these: A, B, C, D, E ,F or G and that would be followed by a number indicating the note's octave.

I'm not really familiar with how cubase SL handles midi data. I don't know what O-Node is..but I'll check out the SL doc and see if that can shed some light on this.

How are you entering the midi notes, just via the midi editor or are you using something else?

I-Note and O-Note are what Cubase refer to as input note and output note, meaning what note is received and what is sent out when a note is played. I'm sorry, I meant O-Note, not O-Node.

I enter the notes in a MIDI map that allows you to define each MIDI track. You can select the I-Note and O-Note.

Your idea about note and octave makes a lot of sense. I will try and confirm that on my gear. If this is how they do it them I am essentially screwed, because there are literally hundreds of different sounds on the Zoom, far more than there are keys on a keyboard. Maybe they go past the range of a standard keyboard, but I'm not sure.

This is some good info for me to start with. Thanks very much. I'll post anything else I find.
