Thanxs so much for helping me.. While I was awaiting a Samaritan reply I thought that in case no reply I would have kept keystep master clock and connect the blofeld to pyramid midi A leaving the midi B empty for a future another machine.. But maybe to symplistic..and probably wrong... Cheers
No, not at all. The simpler the better. My reasoning for using the Pyramid as the master was due to a) It has a display that will tell you exactly what BPM you are running at as well as it doing 10th's of a BPM, the draw-back to this is the tempo setting doesn't have a dedicated knob. Reason b for thinking that way was I was tired (lol).
I remembered last night after posting, when using the Pyramid, the way to merge data on the MIDI in port is to tell it in the MIDI menu to THRU MIDI from the in to one of the outs.
Running with the Keystep as master would mean single-touch tempo control but only a guestimate of the actual tempo. I can't remember if the Pyramid does display external tempo on it's screen (I actually haven't used it for awhile). You'd have to set the Pyramid to sync to external MIDI and as with the other solution, tell the Pyramid to THRU the MIDI from the DIN in to the output the Blofeld is on. Also the Pyramid can be told to send tempo data to any, all or none of the MIDI outputs. In factory default setting, it's set to send on the two DIN ports and the USB port, so you shouldn't need to change this, but always worth checking.
With only three devices, it's not too hard to fumble around with MIDI for short time before working out the best way to patch it all, but a little nudge in the right direction makes it all a little less daunting. MIDI is made out to be a perplexing protocol at times, but that's played up a good amount and with a some patience and reading, you can get the basics and more under your belt.
With regards to the CV ins and outs on your gear, I have used the ins and out on both the Pyramid and the Keystep. I've run an MS-20 off both with great results, and clocked a Pocket Operator with the Keystep. Now I remember not having to gooder results with the Keystep due to it transmitting a not-so-hot trigger voltage, so the PO was having troubles sensing it (so I clocked a Volca Beats with the Kestep then clocked the PO from it). I'm not too up on how the Keystep goes as a CV keyboard controller as I've not tried out like that yet, but I have used both pitch and velocity CV's as modulation sources for the MS-20.
I'd hazard a guess that the Pyramid would be able to process the various CV's from the Keystep though you'd have to go into a menu to configure what the two CV's are controlling. Doing it that way would mean you could run the Keystep as master and will give you a free MIDI DIN port to feed another synth with that you might only want to sequence with the Keystep. I actual have mine going directly into my Tetra with it then being passed onto my MIDI patchbay, that's how much I think the two suit each other. But I don't run anything via it's CV, yet. I'm three modules into a modular synth though, so I know that will change before the end of the year
