ANSWER TO BONUS QUESTION
Turning an U PSAW into a DNSAW means that we are intending to reverse
or invert the direction of the UPSA W's waveform. To accomplish this, simply
set the POINT Values so that the TRAC K's normally positive-linear output is
inverted to a negative or inverse-linear output. Use the following settings:
POINT 1
POINT 2
POINT 3
POINT 4
POINT 5

The RAM P
I
PORTAMENTO Sub-Page contains three independent
controllers: two Ramp generators that allow for linear modulation and a "Lag
Processor'' circuit that produces Portamento.
The RAMP Generator
The two RAM Ps in the MATRIX-GR produce a type of modulation that can
be best described as a smooth, linear transition that resembles the Attack
portion of an envelope. When used as a modulation source, the RAM P
starts is cycle when it receives a trigger (a kind of "go" signal) from the
M aster controller, one of the LFOs or an external source through the
PEDAL2 jack. It then begins to generate an increasing control signal
gradually u ntil it reaches its maximum. The time that it takes to do this is set
by the RATE parameter.
40 RAMP 1 RATE
42 RAMP 2 RATE
When triggered, the RAM P will begin its control cycle. It will
complete its cycle and wait for another trigger to start again. The
MATRIX-GR's MIDI IN from the Master controller or an External Trigger
(input to PEDAL2) serve as trigger sources for the RAM Ps. The time
that it takes to complete one cycle is set by the RATE control. VALUE
range is O to +G3 where O is an instantaneous transition (no time) and
G3 is the maximum.
41 RAMP 1 TRIGGER
43 RAMP 2 TRIGGER
The RAMP starts its cycle when it receives a trigger signal. There are
four types of triggering available with the RAM Ps:
STRIG
"Single Trigger": The RAM P will be activated for a voice
only if that voice is not already playing. This means that if you are
holding a key down, the RAM P for that voice will not start again
(won't get a new trigger) u ntil you let go of the key and play the
same voice again. Single triggering only operates when the
