This statement from the Voyetra Sequencer Plus Gold manual is in the last paragraph here:

They highlight this as an issue for uploading sound banks, but it has another consequence: If I'm inputting notes with a MIDI keyboard, and using an offboard MIDI device like a Sound Canvas for playback, I can't hear the notes as I'm inputting them. I have to record in silence then play it back to hear it. Which is not a very good workflow!

Does anyone know if this is an inherent limitation of the Sound Blaster / compatible MPU-401 interface? I've been googling but can't find it explicitly spelled out anywhere else. Simultaneous MIDI IN/OUT is a pretty essential function for music creation, and seeing as Creative sold MIDI breakout kits for this purpose, it seems odd that you can't do it.

Has anyone been down this road with Voyetra? Are my only alternatives a Voyetra, Music Quest or Roland interface? Does the Gravis Ultrasound have this limitation too?

For the record my card is an Addonics SB Pro compatible based on a YMF-701S.

That's why you use MIDI THRU to send your keyboard to both the sequencer and the module at the same time.

Modules: CM-64, CM-500, SC-55MkII, SC-88 Pro, SY22, TG100, MU2000EX, PLG100-SG, PLG150-DR, PLG150-AN, SG01k, NS5R, GZ-50M, SN-U110-07, SN-U110-10, Pocket Studio 5, Dreamblaster X2, McFly

SBs use software based UART, which is source of all its limitations and bugs. Everyone else has a proper hardware UART without any such problems.

Unfortunately I'm limited by my input devices - an entry level Behringer keyboard and a Rock Band guitar, both with MIDI out ports only.

So this is just how it is with SBs. Good to know, cheers.

You may need MIDI splitter/multiplier that takes one MIDI input and duplicates it to multiple outputs. A step above there are also MIDI routers that provide control over what goes where, but they also tend to be more expensive.

Wouldn't the wiring be:

MIDI Keyboard [MIDI Out] -> [MIDI In] Roland SC55 [MIDI Thru] -> [MIDI In] SoundBlaster

That should be possible with your devices so that you can hear what you are playing. You will have to rewire for playback from the PC, yes. But that's then a limitation of your setup, as you said. Otherwise get Keropi's PC MIDI Card clone! 😀

I may have another option to try while I procrastinate on a PC MIDI card. It turns out Voyetra released an expanded driver pack, and among those drivers is vapiTG.com, a serial MIDI driver for the Yamaha TG100. I happen to have one of these in the stack, but the driver will likely also work with Korg or Roland modules that have a serial option.

This effectivley turns the TG100 into a MIDI interface giving me access to IN, OUT and THRU ports - and hopefully gives me the simultaneous MIDI transmission I'm after. Just need to grab a serial-miniDIN cable and try it out.

A proper MIDI card would still give me the most convenient setup, ie. not having to rewire things for different activities.

Just use the second MIDI In port on the SC55 to connect the MIDI Out on the Sound Blaster. Since the SB can't receive and send at once it should not be a problem (i.e. no MIDI loop).

I've actually had the SC-55 in the chain, purely as a monitor for MIDI input. But that's not the output device I want to drive - I want to use the FB-01, internal OPL3 and maybe some TG100. So I'm recording with different sounds than I intend to capture, which is a little janky.
