5.21 colin’s notes on the shapes and sound:
I've ben using Log3 for most of my patches, but there always seemed to a softness about the attack.
After experimenting a bit, a find the EXP3 to be much more percussive sounding but it also makes
the patch sound "smaller", and you get a bit of air before the sound fully kicks in.
Scurve1 gives the best of both worlds. It has some of the size/thickness effect of Log3 but with the
snap of Exp3, but with less air :)
5.22 setting up envelope triggers:
(from using_a6_public.txt)
ENVELOPES:
There are two levels of Triggering on the Envelopes. Trigger, the top level, allows firing the
Envelope once from the keyboard or any other Mod Source. Pressing the Envelope Trigger
button twice Enables this function.
Note: The keyboard will continue to be the only Trigger until you change the Mode (soft pot
7) to MODTRG or MOD-TG (the latter includes Conditioned Sustain). It is not possible to
have a Mod Source set up to Trig an Envelope but have Trig: OFF, play the keyboard, and
Press Trig to Enable the Mod Source, thus switching from keyboard Triggering to Mod
Source Triggering. You must change Mode to allow this.
ReTrigger, which allows you to fire the Envelope again (and again) AFTER the first Trigger
has been recieved (via the Keyboard or any Mod Source) is found by turning Soft Pot 8 to the
right. The text and parameters update to ReTrig. This allows for several different options. If
you wish for an LFO (for example) to Trigger and then ReTrigger an Envelope, simply set
the Source to that LFO in the Trig and ReTrig pages, and set the Level and Polarity the same
on each page (or differently :)
Note: Only one Trigger Mode is allowed; it is global for Trig and ReTrig.
Polarities:
• Positive: The rising edge of a Trig Source is used to Trig.
• Negative: The falling edge.
• Bipolar: Both are used; nice for double-clocking effects where the Env fires twice for each
LFO cycle, if LFO is the Source.
The three Absolute Polarities rectify any bipolar Trigger Sources.
Note: MODTRG Mode is similar to Freerun, in that when Triggered, the Envelope will run
through it's entire shape. MOD-TG includes Sustain. This Sustain is Conditioned by the
setting of the Polarity parameter. If Polarity is Positive and MOD-TG is the Mode, then a
single positive-going Trigger will fire the Envelope, which will remain in it's Sustain phase
until -another- positive-going Trigger is detected. To have the Mod Wheel, for example, be
the Trigger, and for the Envelope to fire and enter Sustain for as long as the Mod Wheel is
held above the threshold Level and for the Envelope to stop Sustaining and enter Release
when the Mod Wheel is lowered below threshold, use the Bipolar Polarity. Up above
threshold Level: Fires and Sustains; Down below threshold Level, Envelope enters Release.
This of course holds for any Trigger that exhibits duration.
