A 4hp Dual VCO is coming soon. prototypes will be at knobcon
VnIcursal top pcb upgrades are now available. the new top pcb adds attenuation functionality to pre-existing v3 and v4 vnicursal mother boards. so when cv is inserted into the cv jack the pots now become attenuators for the incoming voltage.
a couple things to note: the older revisions are not designed to have the leds turn on close to the 0v crossing. this means there will be a small range of the pot turn where you will be able to hear sound and the led is not on. also since the leds are on more now the circuit will consume around 10-15 mA more on the +12v rail.
and finally some resistors will have to be substituted on the mother board for optimal operation. depending on what version you have you will have to replace six 47k resistors with six 62k resistors or six 75k with 62k. this will give you unity gain at 5v. i will post a pic soon of where those locations are. it isnt completely necessary for the mod but if you dont do it you will notice towards the end of the pot turn the circuit goes from distortion to an almost waveshaping pop.
VnIcursal top pcb upgrades: $10
all modules not already in red/black aluminum come with black and white aluminum pcb panels. replacement panels are also for sale.
attmix b/w panel only
dual vca b/w panel only
entropy b/w panel only
clk dv b/w panel only
mineq b/w panel only
aluminum panels are in for the vnicursal vca. and 2 new 2hp modules are out now(see below).
Vnicursal VCA aluminum panel: $10
Push VCA: 2 independent unity gain dc coupled VCAs with led push button switches to turn channels on and off in 2hp. a mix of both channels is available at the sum. all outs are available simultaneously.great for cv or audio.
aluminum panel. reverse power protected. current consumption +12v @20ma, -12v@ 20ma
MiniAtt: is a 2hp dual passive summed attenuator with toggle switches to turn each channel on or off. both channels are normalled to the sum. there will be some signal loss at the sum out, as the module is passive. great for cv or audio although the module ships with linear pots.
aluminum panel. passive, does not consume any power.
