Re: fcb1010 and ART SGX 2000
Hi. I wrote all this before thinking that you may not have experience with English, especially American idioms. So I'll apologize in advance and ask that, if you have any questions, please ask and I'll try to speak plainly.toggle quoted messageShow quoted text
Ha! No, I don't own an SGX, as I don't play guitar - well, at least not seriously. I've played rhythm guitar in my church, on and off, since I was 15. I do more keyboards and electronic music now. I am in my mid 50's, and have grown up with MIDI, so I've read more than a few of these incomprehensible manuals.
So, a quick MIDI primer. At it's most basic, MIDI can send and receive four different message types. Note messages, PC - Program Change messages, CC - Control Change messages, and SYSEX (System Exclusive) messages. SYSEX is just a very generic way to send big blocks of information over MIDI. It was actually grafted on to MIDI when manufacturers complained they had no way to give their devices initial settings in a fast, easy way. But SYSEX also became the way for manufacturers to make their products proprietary - a.k.a make sure they'd only work with their own software. That has gotten better in the last decade or so, but not much.
Note messages are very simple. They send either a Note On or Note Off message, with an extra byte for Velocity - a number from 0-127 that says how loud a note should be, or how hard a key was pressed. Yes, Note Off messages still include the Velocity byte. It was a programmer thing, and made sense at the time.
Program Change messages are pretty much just what they say - a way to select programs or presets. A lot of manufacturers, either through ignorance or intent, used it in different ways, but it was made for simple selection of presets on a device like your SGX.
Control Change messages were meant to, obviously, control. They change parameters - volume, balance, filter frequency, etc. Oddly, early manufacturers left CC's alone, and didn't use them as much for proprietary controls. They either ignored it entirely or used it as intended, which was great for people like us. CC messages send an extra byte whose lower seven bits are used as the value of the setting. This gives values of 0-127, or 128 total 'steps', which was seen as more than enough at the time, and is still very useful.
The zero based numbering is another confusing issue. I've been a programmer as long as I've been a musician, so I understood it. But people not exposed to the idea have a problem with the 'zero position' having a meaning. MIDI channels were most of the problem. Product developers would say, "People won't understand zero based numbers", so they wrote the manuals saying channels were 1-16, and controls were 1-128. The software guys didn't agree, and when they wrote their 'appendix' for MIDI, it would be 0-15 and 0-127. This made for a whole lot of infighting and 'general hate and discontent'. It ended up having a large effect on the adoption of MIDI. The internal feud between programmers and product specialists made MIDI seem arcane and the companies seem inept. Not to mention that getting a programmer to write a comprehensible manual is like getting a chimpanzee to speak English. Or Greek. :-)
Ok.. back to the important stuff. The FCB1010 can only send PC, CC, and Note messages. For each Preset (every time you press a foot switch), it can send five different PC messages, two different CC messages, and one Note message. Each preset also sets the CC message number for the two pedals. A lot of FCB1010 owners have trouble understanding that: You must select a preset to get the pedals to work. If you never change the pedal settings, they default to CC 07, Channel Volume, and CC 01, Expression Pedal. Channel Volume is usually Master Volume or Gain on pedals and amplifiers.
So, that's a little more than I intended to write, but I hope it has helped you in some way. Keep us updated on the Groups.io FCB1010 forum if you make any progress or need more help.
