If you don't have it, you can grab it from my library in the signature.Īnd in case you're wondering, since Pd-0.43-extended is doing away with loading libraries on startup and adding paths, I'm getting rid of the '.mmb' extension on my abstractions. The helpfile uses my abstraction to display the spectrum. I didn't bother with the bit depth, though, so if you really want to make it sound like early digital, throw in a bit crusher after it. So I basically did some reverse engineering, along with studying the patent, and came up with these. The Thor synth has oscillators that emulate the CZ series. I don't actually have access to a CZ (I did once, and I didn't take advantage.SON OF BITCH!), but I do have Reason 4.

Modulating the phase with these oscillators has a sound similar to a filter sweep, though it is not an accurate emulation. This allowed the oscillators to create unique waveforms using minimal computation and memory. For those of you who don't know, the CZ oscillators were early digital oscillators that worked by distorting the phase look-up of a cosine waveform. This song is pure Casio CZ-1000 with just my patches.This abstraction attempts to emulate the Casio CZ oscillators. Selling it soon anyway since it was just a little repair project. I bet the guys who wrote editors know this already, but I have not got an editor for the CZ-1000 to work yet. Only odd thing I have noticed is that octave settings are not saved over sysex. Nice thing about that is you do not have to save the patch since directly inserted into memory. Change 60 to 20 and you now send directly to internal location 1. How about changing the 60 to an Internal location value, like when reading a patch? Turns out that works, too, and you use the same numbers (naturally) as when reading a patch. Don’t know what 03 00 does, but it is not always 03 00 in the files I downloaded. The first 8 are special since they identify the receiving synth as a casio (44 00 00), to use MIDI channel 1(70), send a patch (20) to the edit buffer (60). So now the process is more tedious than ever but it works.

I sent my modified file to the CZ-1000 and it worked perfectly, but the patch has to be saved to an internal location. I cut out the first 8 bytes and inserted the following 9 from a good file, so I now had 264 bytes. This is where the MIDI-OX sysex scratchpad comes in. Why? They have 264 bytes and the first 9 are different. I sent some patches I had downloaded and they worked. I thought, “Hey, I have a sysex file now so let’s send it back to verify it works.” The files appear to send but the CZ-1000 ignores them.

I read my custom patches one at a time from my CZ-1000 using MIDI-OX. The commands (sysex handshakes) to request a patch are 9 bytes long. The hexadecimal commands and instructions are here. Reading sysex is tedious enough since you send a command at a time to read one patch at a time.
