      I’m trying to use my Boss MS3 to change the Program on the H90 and bypass it at the same time.

      I have the MIDI Bypass CC# set to 0. When I set the configuration like attached, it does indeed bypass the H90 with a value of 0 and activate it with a value of 127.

      However, if I send a PC# along with it, then it doesn’t bypass. In the example attached if I set the PC to anything other than “OFF” it ignores the Bypass CC and turns the H90 into active.

      I tried the same with an H9 and it works as expected, the program changes and the bypass CC correctly sets the bypass state. How can I do this with an H90?

      Looking at the log files I’m assuming the MIDI bypass messages are being ignored:

      ‼️ [TRPCMessageBroker.h:147].midiReceived > Ignoring inbound message ID:0x1d due to pendingResponseID:0x1b
      ‼️ [TRPCMessageBroker.h:147].midiReceived > Ignoring inbound message ID:0x19 due to pendingResponseID:0x1b

      Any information what this means?

      As an educated guess, the H90 Program is still loading via the PC when the CC message arrives, a scant few milliseconds later (if that).  Another speculation: the H9 – even with an older processor – is loading less than half of data that an H90 Program contains.

      I suppose it’s possible to hold incoming MIDI messages in a buffer, delaying it long enough to slide into the MIDI stream shortly after the last command has completed.  As a serial protocol, you’re bound to run into some limitations with MIDI vs. the power of modern processing.

      I haven’t checked back your use case with either an H9 or H90.  If I need a Program (or one of its Presets) to load bypassed, I re-save it with Bypass engaged.  Then use an Act/Byp command as needed.

      That’s really a bother and not something I’d expect from such a high price point. I’ve noticed I’m not the only one with this use case and having to load everything disengaged and engaging it from another preset means I lose the flexibility of having one preset for each program but I would need to have 4 to cover each use case of A/B being bypassed.

      I guess I’ll be returning the H90 and keeping the H9 since at it’s current state the H90 is unusable for my purposes.

      Hello,

      We are aware that there is an issue with this use case and are working on a solution. Previous versions of the firmware should allow you to use the simultaneous PC+CC messages, or if you use Program level active/bypass mappings (not global active/bypass mappings) then that should work as well.

      I’d be happy to help you with this further if you email support@eventideaudio.com.

        I note that ‘previous versions of the firmware should allow you to use the simultaneous PC+CC messages‘.  Is there a previous version of the firmware that will do this that does not also have the issue where presets would load with the wrong delay time (AUD-74364)?

      Just to comment that the Program level active/bypass does not work when sending PC+CC messages. I have tried it several times. No CC messages get recognised after sending the PC. I will contact support.

      Apparently it should work with firmware 1.8.6. I’ll try downgrading it and confirm.

      I logged exactly this problem with Eventide support on 24 January. It’s a pretty big deal for me, also.

      I can confirm that the MIDI switching works with 1.8.6. At least from initial testing. I’ll have to check if it causes any audible difference or lag when using it in a signal chain.

        Which version of H90 control are you using with H90 firmware 1.8.6?
