Receive Sysex From 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 to somewhere you can write the sysex file:
Launch amidi, have it listen to the midi port, and have it write what it hears to a file:
amidi -p hw:0 -r my_sysex.syx
Change "hw:0" to whatever MIDI port you are using. Change "my_sysex.syx" to whatever you want to name the sysex file.
- On the CZ-1, Press the CARTRIDGE/MIDI button to prepare for dumping.
Press PAGE DOWN until you see this screen:
MIDI SAVE OR LOAD
We want to save MIDI data, so press the SAVE button.
It asks you whether you are sure or not:
SAVE MIDI DATA (Y/N)?
Choose yes by pressing the YES button. The CZ-1 starts dumping all data.
SAVE MIDI DATA RUN!
Wait patiently until the process is complete. Don’t press any other keys until you see this:
SAVE MIDI DATA OK!
When the CZ has finished, just hit Ctrl-C to exit amidi. Check to make sure the file arrived:
ls -1 --> my_sysex.syx
The sysex has safely arrived!
