Hello List,

I just have a Midi Keyboard here (M-Audio Axygen 8) and I am trying to get any sound out of it. Unfortunately, I have no Sound Card with Midi Support, so I connect the keyboard via USB (I am aware of the possible latency). As system, I am using Ubuntu Studio 8.04, because it was quite hard to get my sound card working (M-Audio Delta 66), so I did not dare to change to a newer version.

I can see the keys via Jack connector and I connected it to "record in" from rosegarden (http://www.bilder-hochladen.net/files/inr2-1-c4ca-png.html) in alsa tab. In rosegarden, I can see that a signal is coming in and that it records something (http://www.bilder-hochladen.net/files/inr2-3-eccb-png.html). But how do I now get the signal to the speakers? Nothing really works - http://www.bilder-hochladen.net/files/inr2-2-c81e-png.html shows that I have 4 outputs from rosegarden. What I'd like to do is to connect the output from rosegarden to a channel from Ardour.

Can somebody please help?

Greets.

Hi

MIDI isn't a protocol for sound and MIDI devices don't generate sound, the Oxygen 8 is a controller keyboard.

MIDI is a protocol for controlling and interfacing musical instruments -- Musical Instrument Digital Interface -- it doesn't transmit sounds, just messages about note durations, note on, note off, note velocity etc.

If your Oxygen 8 isn't connected to a software synthesizer on your computer (such as a DSSI synth or a soundfont engine in Rosegarden) or a hardware synth or sound module, you'll never hear anything, whether connected with a DIN connector or MIDI over USB.

It looks like you've managed to record the MIDI data you created by playing the keyboard, but there is no instrument for the data to play and make a sound. The M-Audio cards don't contain synthesizers so the General MIDI Acoustic Grand Piano showing in RG isn't actually connected to anything that can make a sound.

I hope this helps.

Best wishes
