a synthesizer enthusiast in the need for your help here
I am trying to understand how to send appropriate serial messages to a synthesizer (Roland JX3P) in order to emulate the behaviour of a rare and expensive nowadays hardware Roland developed in the mid '80s.
The hardware (PG200) was intended as an interface to send tone parameters to the synth in order to create new sounds out of it.
The protocol has just been studied and valuable info are available. Unfortunately I could not get in touch with the original author.
In a nutshell:
- messages are 9 bit unpaired
- messages are inverted before be sent
- a start message has to be sent for the synth to see them as valid
Here is a link to the whole notes the original author wrote
Now, sending midi messages with arduino is a joke thanks to the work of arduino communities all over the world and i have realized some hardware myself (see i.e. Redirect Notice).
Unfortunately, this is a completely different task and I am in the need for some starting hints from valuable coder.
Could anyone help me in figuring out how to assemble and send those messages with arduino?
Thanks in advance!
