The following demos should give you an overview about the versatility and sound engine of this audio processor. All demos are improvised and uncut and there was no further signalprocessing before or after the device unless otherwise noted. Unless otherwise noted also the device was only driven by the sound sources, no controller or sequencer data were used.

At the beginning of each demo you can hear the original sound sources for some seconds.


The typical tonal backgroundnoise in some demos, unfortunately, comes from the on-board-audiochip of the computer (Time by time the capacitors of the computers powersupply are getting dry). SORRY!!

YOUR LAPTOP SPEAKERS AREN'T GONNA WORK FOR THE MOST OF THESE DEMOS! You better use good monitors.

1. A 17 minutes jam on a short loop of a Yamaha Motif starting with four bars of the original loop. The Motif goes into the e&f's main input and the both filters direct ouputs were mixed in a stereo panaorama, additionally the main out is in the center of the mix. No further equipment (EQ's, any kind of processors) are in use behind the e&f! ATTENTION: There is much bass in the mix, you need superb speakers!!

2. Two guitar tracks: ONE electric guitar, directly connected to the main input of the 'ebbe und flut'. The e&f's main output goes into an analogue mixer, the RX-7 Drumloop goes into a second channel of the mixer. On both come a bit reverb and delay. NO further signal processing (dynamics, EQ or anything else!!). For each track only ONE fixed knob setting is used! All changes in sound were controlled by guitar playing and a control pedal, which controls the filter's cutoffs.

3. A simple drumloop from a Yamaha RX-7 runs for 4.28 minutes through the main input of the 'ebbe und flut'. Everything comes only from the audio data, audible at the beginning. The result is what you hear.

4. A simple drumloop from a Yamaha RX-7 runs for 7.02 minutes into the main input. The Audiotrigger and the follower are working on drum loops audio and generate a lot of modulations. The original drum loop is audible for some second at the beginning.

5. A simple drum loop (1.30 minutes) from a Yamaha RX-7 mixed with a doubled sawtooth tone. Both is feeding in the mix the main input of 'ebbe & flut' at the same time. The result is what you hear.

6. Amazing how a sawtooth wave could be fattened and funked up!

7. A 4 minute demo of a sequenzed sawtooth oscillator. The Sequenzer controls the tone height and delivers a trigger for the envelopes and one CV (control voltage) for each filter.

8. Unbelievable what could happen to a cheesy Blues synthline!

9. Extreme liquid - extreme crisp. 2 Filters in love!
Backgroundeffects: delay + reverb

10. Super liquid switch sounds - playing with harmonics! A constant dry synth chord with a slight melody at the bass is feeding the seperate VCF1 input of this unit, a simple drumloop is feeding the main input from where triggers were deviated to control the modulators (ENV's, LFO sync). Both signals were feeding the unit at the same time. Result at the mainoutput (mix of the two Filter outputs) + a bit delay + reverb.

11. A true wav-file of the super fat 24db lowpass mode of VCF1.

12. A true wav-file of the super-smooth VCF2 in 24db lowwpass mode.

13. Electric guitar with automatic wah effects WITHOUT using the pedal or turning any knobs while playing. Sudden level increase by plucking the strings generates a trigger for the envelopes. Backgroundeffects: first and last clip dry, slight reverb for the rest.

14. An electric guitar, directly into the e&f's main in to show only the Distortion unit 1: guitar original (distortion at zero), 2: guitar with slight distorton, 3: guitar with more distorton, 4: guitar with hard distorton, 5: guitar with heavy distorton, 6: combination of distortion and auto filter.
