Programming Basics
Preset Modulation Processors
The preset ramp instantly resets when all notes have been released and the
next first key on the MIDI channel is pressed. The Ramp Rate polarity
(+ or -) determines if the ramp will be positive or negative going. The value
of the ramp rate sets the increment. Large values produce fast ramps and
small values produce slow ramps. Multiple inputs can be connected to the
ramp rate (just like all the other destinations in PX-7).
The patch below shows an application for the Preset Ramp which generates
an adjustable decay envelope ONLY on the first note played to bring in the
sound from another layer. Instead of routing the output to the Amp
Volume you could just as easily route it to control Pitch, LFO Speed or any
other destination you can think of. Study this patch if you want to learn a
few new tricks using the patchcords.
1. DC - Sets initial ramp Fast-Positive (+100)
2. Decay Knob - Inverted value slows ramp as the knob value is increased.

The combination of the
DC & Perc. Decay Time Cords
has the effect of reversing the
Percussion Decay Time knob.
The decay time increases as the
knob is turned up.
3. Ramp Out Cord - Inverts Ramp slope (downward).
4. Amp Vol - Initial setting is Off (-96dB). Ramp cannot overcome this
negative bias.
5. Perc. Amt - When this knob is turned up, the positive bias on the Amp
is restored so that so that the Ramp can now affect Amp Volume.
6. Volume Envelope - Fast Attack, Full Sustain, No Release
