Send Sysex To CZ-1 Using amidi
- Make sure your cables are connected in the correct order. OUT from the computer goes to IN on the CZ. OUT from the CZ goes to IN on the computer.
- Make sure the PROTECT switch is set to OFF. This is a slide switch on the back of the CZ.
- Make sure the CZ-1’s MIDI system is turned on. The LED above the MIDI ON/OFF button should be lit.
Press the MIDI button. To make things simple, we are going to use default values and MIDI channel 1 everywhere. Apply the following settings:
POLY Polyphonic mode KBCH=01 Sending on MIDI channel 1 CH=01 Receiving on MIDI channel 1 PRG=ENA Program changes enabled
When you’re done, your LCD should look like this:
POLY KBCH=01 CH=01 PRG=ENA
You need to know what port you are targeting with amidi. Your CZ is connected to a physical port on your computer, but what is that port called, according to amidi? To find out, open a terminal and do this:
amidi -l --> Dir Device Name --> IO hw:0,0 EMU10K1 MPU-401 (UART) --> IO hw:0,1 Emu10k1 Synth MIDI (16 subdevices) --> IO hw:0,2 Emu10k1 Synth MIDI (16 subdevices)
At this point, you can test to make sure amidi is getting messages from your CZ. Start amidi in dump mode:
Now press a few keys on the CZ keyboard. You should see note on and note off events immediately. If not, amidi can’t yet talk to your CZ. Press Ctrl-C to exit dump mode.
Make your CZ-1 ready to use sysex tone data. Press the MIDI button on the CZ, and press the DOWN button. Please set SYSTEM EXCLUSIVE TONE DATE=ENA.
When you’re done your LCD should look like this:
SYSTEM EXCLUSIVE TONE DATA=ENA
Open a terminal, and change directories until you are in the same directory with your sysex file.
cd /path/to/sysex/files/ ls --> czwigout.syx
Next we use amidi to send the sysex file to the MIDI port:
amidi -p hw:0 -s czwigout.syx
Change "hw:0" to your actual port, and change "czwigout.syx" to your actual sysex file. amidi immediately begins sending the sysex file out to the MIDI port.
