SysEx to Yamaha THR5

Hi, I’m thinking of buying a MC8 and one use would be to use it to control my THR5 amp.

I’d like to know:

  • The THR5 is typically controlled by PC via a USB cable. Would the MC8 be able to be connect directly by USB cable to the THR5, thus removing the need for a PC?

  • THR5 MIDI SysEx commands are quite long (at least 276 bytes, see sample below). I downloaded the MorningStar editor and can only see Length/P1 (1 byte) + P1 (1 byte) + P3 (1 byte) = 3 bytes for SysEx messages. How would I send a long SysEx message?

  • On an unrelated note, is is possible to connect a Wah Pedal to the MC8? How would that work or be configured?

Sample THR5 SysEx message:
F0 43 7D 00 02 0C 44 54 41 31 41 6C 6C 50 00 00 7F 7F 43 4C 45 41 4E 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 4B 64 32 3C 45 00 00 00 00 00 00 00 00 00 00 00 00 00 3D 26 01 00 02 06 00 00 00 00 00 00 7F 00 0B 12 0A 32 32 00 00 00 00 00 00 00 00 00 7F 00 0A 15 02 09 78 00 15 0F 00 00 00 00 00 00 00 01 00 05 00 01 00 32 31 1C 07 0A 49 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 7F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 30 F7

Hi there,

  1. No, the MC8 is a USB device, and likely so is the THR5. You’ll ned a USB MIDI Host converter to connect the MC8 to the THR5 via USB.

  2. Max length for SysEx on the MC8 is 47 bytes, so it’s not possible to send the sample SysEx you specified.

  3. It’s not possible to connect a Wah Pedal to the MC8. Do you mean an expression pedal?

Thanks for your prompt reply.

  1. Any plans on your roadmap to allow longer SysEx messages to be sent?

  2. I mean an pedal that could be configured to control a wah via morningtar. I assume expression pedal. Sorry for my ignorance. Any recommendations on brands that would be compatible?

Thanks in advance.

Unfortunately, there are no plans for longer sysex messages due to storage limitations.

oh yes, for expression pedals, do check out this thread from other user recommendations: Expression pedals compatible with Morningstar? - #21 by teabandito
