Synchronizing Channels: Making Notes Using Triggers
With the previous patch, the tempo of each channel is linked to the rise and fall times of the envelopes.
It’s not possible, for example, to have quick, short notes at a slow tempo. It’s also nearly impossible to
adjust the sliders so both channels are going at the exact same tempo.
By turning channel A’s
Cycle
off and patching the
EOF
trigger from channel B to channel A’s
Trigger
jack, we can synchronize the channels and separate channel A’s envelope length from its tempo. Try
doing this now.
Every time channel B ends an envelope and begins a new one, an EOF pulse fires, causing channel A
to start an envelope. Channel A’s
Rise/Fall
sliders control the envelope length without changing the
tempo. Channel B’s sliders control the tempo for both channels as well as the envelope for channel B.
If you want to decouple channel B’s envelope length from its tempo, you could turn off
Cycle
and patch
an external clock or LFO into channel B’s
Trigger
jack. Now the external clock controls the tempo and
each channel’s sliders independently control the envelopes.
Adding Chaos
You can create some inter-related pattens by patching Channel A’s
EOR
jack into Channel B’s
Trigger
jack, leaving
EOF
patched to Channel A’s
Trigger
jack, and turning off both
Cycle
buttons. Now both
channels trigger each other. For some extra chaos, patch the
Env Out OR
jack to one of the
Time CV
jacks, and patch the
EOR
jack into the
Cycle
jack instead of channel B’s
Trigger
jack. Press one of the
Cycle
buttons to start the chain of events, then play with the sliders, the
Rise/Fall CV
knobs, and the
Level
and
Offset
knobs until you find sweet spots where random patterns emerge.
