Hi there!

I got all this gear over the last months. Geting on with the monologue, then the 2600. The last pieces of gear
is the drum synth from Vermona and last but not least, the Pyramid sequencer.
All I want is to connect that gear and have it all recognised with the Pyramid.
I got some ressources for exemple on a forum where the guy has problems setting the Vermona and the Pyramid
to "talk" toghether. I've followed the procedure but it won't work properly. Vermona won't get mapped as it should.
The Vermona runs 8 MIDI channels. The process is to switch 2 channels trigs while powering up the Vermona. I've
tried that while on the Track Mode of the Pyramid. I've banged my head on this.
Then I thought I'd try something more simple. So I Hooked on the Monologue. Then again, I' ve got nothing out
of it. Those two don' t like each other... or is it me? Likely so!
I think I've try the MIDI IN and MIDI out cabling for the Monologue and the Pyramid. The Pyramid has one MIDI IN (DIN),
a MIDI DIN OUT A and a MIDI DIN OUT B (with sync) as well as a USB IN/OUT I think. I do use DIN cables though.
I've run out of solutions. I have documentation on the Pyramid, Vermona, Monologue, everything printed at home. I've
been refering to it and I keep doing it but I'm certainly missing out on something so that's why I turn to you before I go

ps: I've just printed " What is MIDI. pdf " from the site. I think human help is so much valuable at some point. Cheers.

You've got a fairly complicated set up, and I'm not familiar with any of the specific devices.

Try to get something simple, like 2 devices, working, then add further devices to the initial setup.

Keep in mind which device is generating the midi instructions, and which device can only respond to data received. Connect the midi OUT of the device that is creating the data to the midi IN of the device that needs to receive.

If things get more complicated then you might need midi THRU, which is a variant of the OUT port which receives the data at the IN port and passes it on unaffected by the device, to allow daisy-chaining. You can get midi hubs, which may provide extra ports to interconnect more devices, and I believe there are hubs that are more intelligent, i.e. to do different things with different data.

Thanks for your reply Geoff,

Actually, I have only a couple of devices connected so to avoid too much bother.
I tried his simple thing: playing a (mono) sequence out from the monologue to
let's call track A, channel A1 on the monologue. I arm record on the pyramid (MIDI
sequencer). I press play to launch the sequence from the monologue. As soon as
I've done this, the sequencer goes on record mode. So at the moment, it looks
there might be some kind of connection going, like sync or something. Trouble is,
No playback sounds there - and checked it out, no notes on the sequencer.
2nd, I drew notes on the piano roll of the sequencer. As the Pyramid is a MIDI only
device, you have to hook it up to a sound module. I got the Monologue ( keyboard+
sound module/ synh) hooked up to the Pyramid sequencer. SEQ out to sound module in.
Well, that won't work either. I'm out of ideas there.

Thanks for the info.

First thing, all devices send data on certain channels, 1-16 (or in terms of the midi data, 0 - 15). Receiving devices may be set in different ways, but they may receive data on certain channels as well. If you send data on Ch 1 (because that's what the keyboard defaults to), but the receiving device is set to Ch 2, then the receiving device will see that data is coming in, but will not 'play' it as it's on the wrong channel. On the basis of what you describe, this MIGHT be what's happening here.

Try to see what Channel the data is set to on the sending device. Check the manual for the receiving device and see what it defaults to, and try to be sure they are BOTH using the same channel. Or channels, your sequence could have data on more than one channel at the same time.

Why are these things so fussy? Think of performers who may have a big sequence and many keyboards. Each keyboard can be set to receive data on just one or two channels, so the data from the sequence may all go to all keyboards, but only the correct keyboards will take notice of their part, and will disregard the rest.

You might find it a help is you could create a sequence that sends a few notes on EVERY channel, i.e. 1 thru 16. Make each channel a different instrument. Then see which ones actually 'sound'.

Many keyboards may have default settings, and without being told, they will 'hear' data on that channel ONLY.
