Paul's right on regarding inherent limitations in the PC keyboard
protocol.
I'm not sure how you're using Freewheeling - for instance, if you've
set it to play loops while the keys are pressed down, but not when
they're released, this won't help, but - in the standard config, with
tap tempo and sync on, I've been able to start/stop multiple loops "at
once" by sort of rolling my hand across the keys I want to hit - so
that I'm not hitting the keys at the same time, but within a short
enough span of time that it's still musical.
Ultimately, the cheap midi foot controllers now available make it an
easier system to work with, simply because it frees one's hands to
play instruments, gesture wildly, etc.
Yes I tried to roll, but it's very difficult in some condition and
sometimes one or more loops doesn't start due to this keyboard limitiation.
Maybe I should work on this more like learning a new instrument...
Also, I don't make music alone it's impossible for what I want to do,
one control, one play and vice versa, I don't plan to make music like
with a jamin guitar pedal effect.
I don't know exactly how I will achieve this, maybe by learning more
precisely my keyboard behaviour and configure the look of freewheeling
to help me in that way.
I want to be able to make the music evolutive and it's the main reason
why I need to activate/desactivate multiple loops.
I don't know how to explain clearly what I want to do, maybe I could
define it as a mix of dj style music (with predefined loops samples a la
dj shadow) and instrumentals to be short. I hope freewheeling will help
me in the way to make it impossible to distinghish what was instrumental
(played live) and what comes from samples.
