Suggestions/help for processing binary sysex

[EnzoF04]

I get a midi message from my synth. The data / parameters are spanned over several bits in 16 bytes. I want to process the sysex in binary format. How can I do this.
My plan is to pull clusters of bits from the sysex data in binary format and push them into decimal variables to be assigned / set into modulators on my panel.

Any one have an suggestion how to do this?

The first 5 bytes are in the attachment to get an idea how the parameters are spanned over the bytes.

Thanks for all help!

Hello.

There are functions (methods?) to get/test bits in bytes/bit-positions. You could then assemble a normal byte to represent the single synth parameter byte. I’ve not tried this (and I’m no Lua expert) so you may need to experiment a bit. Maybe it’s somewhere to start.

getBitRangeAsInt (value, startBit, numBits) : Get’s a number of bits (numBits) starting at position startBit as an Integer and returns that integer.
setBitRangeAsInt (value, startBit, numBits, valueToSet) :
clearBit (value, bitToClear) : Clears a bit at position bitToClear in the value and return that modified value.
isBitSet (value, bitPosition) : Return true if a bit at position bitPosition in value is set, false otherwise.
setBit (value, bitToSet) : Set’s one bit in an integer at position (bitToSet) and return the modified value with the bit set.

Thanks for the reply, BillFM; I’ll get into it! This is what I think I have to do with the received data. I have to learn more. Thanks for your input! 🙂
