CTL1 – Touch Panel
Rev1 – Jan2010
Overview
The CTL1 Touch Panel combines a 4-Key Touch Controller with 3 rows of a 4-Stage Preset Sequencer. The Touch
Pads generate individual CV Pressure Outputs, plus a Common Pressure and Common Gate. The active step of the
Preset Sequencer is selected either by using the Touch Pads and Step Input.
Controls
1.
Step Input
– Any voltage over c.+1.5v will clock the Preset Seq stage selection [dependent on Direction
Switch]. While a gate / clock signal may typically be used, any waveform that rises above 1.5v will work.
2.
Row Range Switches (1 – 3) –
Individual range selection switches for the three Rows – 10v, 5v, 1v.
(Voltage levels are preset on the rear of the module)
3.
Direction Switch
– Activates the Preset Seq clocking and selects left or right shifting of the active stage.
4.
Individual Pressure CV Outputs (A – D) –
Key Pressure voltage outputs for the four individual keys.
Output range is 0v (inactive) to +10v maximum. (Pressure response is preset on the rear of the module)
5.
Individual Pressure LEDs (A – D) –
Indication of the Pressure voltage outputs.
6.
Common Pressure CV Output –
Summed output of all four Key Pressure voltages (0-10v range)
7.
Touch Pads (A – D)
– In general the keys respond in a monophonic way (ie. Press one key at a time).
When pressing a key the selected stage is 'held' (ie. Clocking is deactivated)
8.
Preset Dials –
Three rows and four stages to set Row Output voltages. Only one stage is active at any
time, but the three rows are independent.
9.
Stage Active LEDs (A – D)
– Showing the active Preset stage.
10.
Individual Row CV Outputs (1 – 3) –
Outputs for the three rows with range governed by the individual
range switches.
11.
Gate Output –
The gate output goes high (+5v) whenever any touch pad is pressed. When not pressed the
gate output is 0v.
