[linux-audio-user] Connecting a MIDI keyboard

Folks, What looked simple is not. I have this Yamaha Psr-260 keyboard. I want to use it to play the ZynAddSubFX synth (one of these days I'll know how to write that name I guess, if only by multiple repeated tries). So I start a MIDI cable from the OUT of the keyboard and connect it to the IN MIDI jack of the M-Audio 1010LT card. So far so good I guess. Then I start jack using Qjackctl, and press the green button. I also start the ZynSubAddFX synth (looks like a Polish name, guess that was the spiritual connection) and it shows up in the jack connect dialog box, which looks like this: Readable Clients / Output Ports + 14LMidi Through - 16:M Audio Delta 1010LT MIDI 0:M Audio Delta 1010LT MIDI Writable Clients / Input Ports - 129:ZynSubAddFX 0: ZynAddSubFX So I connect the last two entries together. The Zyn synth panel shows MIDI channel 1 selected. Jack uses the ALSA driver. I play a few notes on the keyboard and only the built-in Yamaha sounds are resounding, no Zyn. If I use the Zyn virtual keyboard, I can hear the software synth all right. The mic input of the 1010LT works fine, as well as the rendering of sounds made by Zyn and Hydrogen. So I presume the card is OK. Maybe the MIDI cable is not, so I changed it. To no avail. Systems are Fedora 5 CCRMA and Studio64. Is there something else to be done in order to use a MIDI keyboard to trigger sounds created by the Linux box ? Or should I start to think that the keyboard itself is somehow damaged ? Al
