Audio Demo's

Here are some audio demo's to illustrate the possibilities of the LFO expander.

Audio demo 1: ARP2600 vibrato

2 oscillator melody. The first time without using the LFO expander. The second time, oscillator 2 gets vibrato from the LFO expander. The third time, oscillator 2 gets vibrato + bend (1 octave up) from the LFO expander.

Audio demo 2: ARP2600 vibrato fm

Frequency of oscillator is modulated by LFO expander on high speed.

Audio demo 3: ARP2600 wah-wah

Simple melody. Filter cut-off frequency is controlled by LFO expander. Note how the speed and depth of the LFO increase when the foot pedal is pressed.

Audio demo 4: ARP2600 filter sweep

3 oscillator drone. The manual-knob on the LFO expander was used to sweep the filter cut-off frequency. Turning a round knob gives more control than moving a slider...

Audio demo 5: ARP2600 LFO-speed keyboard tracking

The ARP2600's keyboard CV is fed into the pedal input of the LFO expander. The higher the key played, the higher the voltage going into the LFO expander resulting in a higher LFO frequency.

Audio demo 6: ARP2600 FX

Pitch modulation: starting with the pedal pressed down and slowly releasing it.

Audio demo 7: ARP2600 pitchbend

Demonstrating the range of the sweep function.

Audio demo 8: summing two CV's (sequencer fun)

Again the ARP2600. This time an analog sequencer (Doepfer MAQ 16/3) plays a well known Vangelis sequence in C. The output of the sequencer is routed into the sweep-path while the sweep-knob is adjusted for a 1:1 ratio. The keyboard CV is routed to the CV input. Now, the sequence can be transposed by playing different keys on the synth's keyboard; both CV's will be mixed together !

Audio demo 9: CS50_1 Audio demo 10: CS50_2

Just two simple melodies demonstrating the LFO expander connected to a Yamaha CS50. Note how the speed of the LFO is affected.

Audio demo 11: CS80

Bassline from the ARP2600, chords on the CS80.
