There is a huge difference, I could say, a light-years distance, between playing only synthesizers on realtime, than having a computer hooked to them.
in fact, I only look to the screens of the synths to see wich pattern is actual playing.
1. I can only use USER patches. Because some parameters of the patches must be modified to interact with other synths.
2. I've been programming-working on creating sinergy between the synths during several years.This is a long term proyect, each time I add a synth to the MIDI net, I know I'll have to spend one or two years more on reaching my goal.
Each synthesizer work as a part of a huge collective, they need group mentality, I take the pros of some synths to heal the contras of other synths.
In this MIDI net, if just one synth fails, all the others will crash, the relations and interactions of the synths are very complex, in order to produce new properties that you won't find on each of them. Even making them sound at the same time with a mixer in the middle, can't reproduce the effect of a continuous MIDI chain of all the synths pumpin as a single huge machine.
3. I don't use song mode. I use patterns of several lenghts, specially 4 and 8 measures patterns, but also, 7, 3, 32, 15, etc. I stay on a pattern, I imaggine on my head what's next, and I choose the next pattern.
I have several patterns at the same time. Because I programmed and composed everything (not a single sound, or track from Internet, or CDs, or factory presets) I know where is everything. This is an aproximmation of the USER info I have stored on each synth on its sequencer.
XL 7: 770-800 patterns.
MP 7 680-700 patterns
MC 909: 200 patterns, 30 pattern sets
EX 5: 200 patterns on 4 groups of 50.
Motif 200 patterns...
Electribe: 180 patterns.
etc....
etc...
SP 808: more than 12.000 samples, all of them ready to trigger. Not a single one from Internet, or Cd, or record of anybody.
Each sequencer has its own way to work, because all the synths have great differences on concepts, ways of manipulation, tools of recording, etc...
each pattern has its own personality, when I play pattern 18-7 of the XL 7, at the same time with the 18-7 of the MP 7, and the 18 of the EX-5 and the 18 of the Electribe, they will interchange info, they will talk with each other, will send commands and orders thru all the MIDI net, ordering tto the other synths, to position on determined sound, on determined knob position.
Everything is available to manipulate on the act,I have practice a lot to manipulate the BPM in a manual way, so they will keep the beat right.
I have a history on mi mind, before each 2-3 hours of presentation. I just need where is everything, and then, I can play a song with sense, with a soul, with Gestalt properties.
There are properties on songs that are only perceived when you listen them from the beggining to the end. that misterious information appears as a image, apart from the song, only when the song ENDS. That's the result of processing in your brain a serial of musical information on ANALOGIC and serial process. What you play on the third minute, will have consequences on the minute 5, the second song, will affect the way you enjoy the song 9. This only happens when you hear a set from the first to the last song.
IMHO, making music on computers, is like, renting a movie and see 20 minutes of this movie each day. You can say, I saw the complete movie, but it will never, never compare with looking the movie from begginning to the end without pressing2 "Pause" on your DVD.
That's why I combine the rigid, systematic objetive procedure of STEP-REC, pre recorded tracks, orders, command, with the subjetive poetic process of interacting as fast as you can, with your soul on your fingers, with those rigid commands that rule on electronic music. One method put the order, other, the caos and aleatory laws. Like nature. Each cloud has a pattern, but also, an aleratory, chaotic and misterious ingredient, that makes them all different. Maybe that's the reason I've never repeated a song in my whole life, in exactly the same way.
Bcause how you can put your feelings on the music, if you're not actually playing it? Are you gonna stop the feeling, go to the bathroom to take a piss, and come again, and say... well, where the hell I was...??? O yeah!!! I was feeling this and that...
Is ironic, I've spend months composing a single tune, but my best melody, a song that has a 4 minutes crescendo pads solo, was composed in that: 4 minutes.
I couldn't change the feeling I feel when I play music in this way, even for all the money of the world. I'm not just another watcher, maybe I'm the person that is enjoying the most on the party. Is necessary to walk a long, long way to achieve this, but it worths every drop of blood in your veins, cause playing musical instruments on realtime, creating a melody on the moment, with a synth, a piano, aguitar, whatever will always be the best way to make music.
sorry for the long post...
