Like making sure that what's needed by the box(s) next in the chain get that info WITHOUT affecting the unit that gets the info to be forwarded. There are other concerns when using a MIDI-chain (i.e., MIDI in to out to in to out to in.): Yes, I still have MIDI delays but it's a known constant throughout my studio since all MIDI synths/gear has I/O to the MIDI patch bay independent from all other MIDI synths/gear. I have a lot of external MIDI gear but I use multiple MIDI patch bays (they each route up to 8 MIDI I/O pairs - independently they are analogous to AUDIO patch bays). If you have an audio timing critical situation then you may need to do some sequencer adjustments and 1) lag your internal audio and/or other internal MIDI plug-ins, 2) lead your external gear by a little ( a few MS), or a lot, depending on which unit is first in chain and which is last and which generates sounds first and which generates sounds last, etc, 3) record each external units sound on separate audio tracks then adjust time later (after recording) by sliding that units audio backwards (or other PC audio forwards), etc. If these are SOUND generating units (i.e., external synths) then the audio delays MAY, or may not, become a real audible/timing issue - it depends on your situation for each song. ![]() If these external MIDI units are just audio FX units, like you mention (reverb's, compressors, etc.) probably no big deal (but it depends). See this thread and look about 6 down to one by "JCRC" With three (3) "In's-to-out's" the delay is PROBABLY around 15 (or MORE) MS for last MIDI box depending on the various actual HW units (15 MS is allowing an average of around 5 ms for EACH I/O pair) More than two or three chained MIDI units and the MIDI delay might start to be too noticeable - even just two could be an issue for you.ĭelay can be a few MS (milliseconds) in each box: MIDI-in hits the internal MIDI processor which then decides what's internal use and internal routing, then what needs re-routed to the out port (that all takes finite time) ditto in next box so you can see the delay's adding up. If you only have a few, three or less, and you chain "in's to out's" like you mention you are probably OK. You asked multiple complex question(s) I will mainly address the external MIDI gear situation. This is ALL just my opinion and how I do things #341069 - 03/20/16 11:43 AM Re: Finally connecting my studio up - what to do for MIDI ?īefore my long winded response pghboemike hit it on the head - better help will come to you if you LIST what you have and how you plan to use it Digital Synthesizers - should all 3 be on separate disk drives, or is it OK if BB/RB and Digital Synths are on the same drive ?Ĥ.) Any other gotchas or advice when connecting so many devices to your computer ?įeel free to answer one or as many points as you like - and as always, thanks to all of you who generously share your experience. Is there recommended software/hardware for controlling mulitple effects processors and synths during live performance ?Ģ.) I have about 4 boxes that accept USB connections to my computer.Ī.) Can I use a powered USB hub to control all 4 - or would that lower throughput so that each should be directly connected to the computerģ.) Where to install BB/RB vs. Are there other practical uses - or am I studying connectivity for no practical reason ![]() Are MIDI messages to effects boxes mainly for toggling effects for different songs and different parts of songs ? Can it all be done from BB/RB ? Is there even a reason to do this ? Having never used MIDI cables to connect and centrally control all devices:Ī.) Do I simply go from my Presonus Out to a first IN, then OUT to IN - until the last box with the IN only ? Is it worth buying a central MIDI interface box to simplify connections.ī.) With what software and from where would I want to control my Effects boxes and program changes ? I have a few questions I thought you might help me with:ġ.) I have a few different effects boxes - most have only MIDI IN and MIDI OUT, one has a THRU also, and one only a MIDI IN. My central rig will be a Presonus Firepod connected to my PC, with BB/RB as the main DAW. I have collected various studio items over the last few decades - played around with each for a short time - never got all to work together from my computer.
