Bill of materials

Draft BOM

The table below gives some of the stuff needed

• LM3916 LED driver
• TL074 op amps
• Condensators
• Resistors
• LM7812 and LM7912 for power supply

Potentiometers

The table below states the potentiometers needed (all pots are linear if nothing else is mentioned)

Nr	Function	Value	Remark
1	Preamp gain	50k log	Lower values will decrease the gain range
2	VCO Freq	100k
3	VCO PWM	100k
4	Supersaw Wet/Dry	10k	Depends on circuit, but this seems the most appropriate. Passive circuit would use stereo 50k pot
5	LFO Rate	10k lin
6	LFO Amt	10k lin
7	EG Attack	1Meg log
8	EG Release	1Meg log
9	VCO/Ext mix	10k	Same as nr.4
10	VCF Width (Q)	50k lin
11	VCF Freq mod	50k lin
12	VCF Res	50k lin

Not mentioned:

• Super saw spread? => 1M rev log
• Main volume => 100k log?
• Octave selection => Also 100k lin -> Strange???

Interessant is om voor de Osc gebruik te maken van een dual concentric pot -> Dan kun je beiden bedienen vanuit 1 plek!

IC’s

Count	Function	Type	Remark
4	VCA	AS3364	Quad VCA, so we need 4
16	VCF	AS3350	Dual VCF, so we need 16 - each IC for one channel
1	VCO	AS3340
1	CMOS Timer	NE7555, TLC555CP	CMOS version of the 555

Knobs

Count	Function	Colour
2	Dual knob	Gray
3	Single knob	Blue
8	Single knob	Red

Knob colours correspond to function:

• Gray = frequency;
• Blue = (direct) sound level;
• Red = CV.
