EDP Wasp synthesizer & EDP Spider sequencer

via this auction

"WASP
Plus Points
When the 9 volt DC mains adaptor is connected and an audio lead is connected to the Line Out and the Wasp is turned on, it emits a continuous note. This frequency/sound of the note can be affected by certain controls such as:
KEYBOARD section 'Bend' and 'Glide' affect the frequency/sound of the note including adjusting white tuning screw
OSCILLATOR 1 section all 'F.T.' settings, 'Width%' and Wave Form control affect the frequency/sound of the note
OSCILLATOR 2 section all 'F.T.' settings, 'Pitch' and Wave Form control affect the frequency/sound of the note
CONTROL OSC. section 'Freq', 'Pitch Mod', 'Noise Signal' and wave form control affect the frequency/sound of the note
FILTER section 'Freq', 'Q', Band Control and both 'Control' knobs affect the frequency/sound of the note
OUTPUT 'Volume' and 'Power On' does work

Minus Ponts
However, the 'ENVELOPE GENERATORS' Sections do not affect the frequency/sound of the note. If I touch any note on the keyboard it does not respond. I have tried adjusting the white keyboard touch sensitivity screw (just above keyboard) and this has no effect. Does not make any sound from internal speaker, just a hum.

Please Note: The second photo shows 4 controls have been replaced.
Typically 4 of the yellow tops went missing and I replaced these with new knob/tops from Clocktronics. The original 4 Wasp knobs with no yellow tops are part of the sale .

SPIDER
Plus Points
In the past this used to work when connected to the Wasp and using a Boss DR55 I could stop/start a sequence by connecting to the 'Sync In'.
Minus Points
Now - Even after connecting the LinkCable I do not know if the Spider works because of the problem with the Wasp - see above."
