TKB/VCM crosstalk?
2003-12-11 by jan-hinnerk.helms@t-online.de
Dear SMOG,
I finally made the step and now have my own Animal and a [TKB]. But on
running some first tests, I encountered the following phenomenon and
would like to ask you to confirm if this is normal or not.
In short: If I use a row of my [TKB] to control one section of my
[VCM], the clock pulses triggering the [TKB] and KP can be "heard" in
the audio running thru the [VCM].
To verify if this is the case on your system, here comes the very
simple patch:
- Patch [DTG] to cycle
- [DTG] Gate out to [TKB] clock in
- [TKB] KP to hold input of [TKB]
- [TKB] row D to VC in of [VCM] middle section
- [NTO] or [PCO] sine to [VCM] middle section In2
- [VCM] middle section out to [UAP], from there to monitor
- Set [NTO] or [PCO] to audio range, bass register works best
- Set [DTG] rise and fall controls so that [DTG] oscillates at 2 to 10
Hz
- Set [VCM] middle section VC pot to zero
- Press and hold any step on your [TKB]
- While holding the step, turn this steps's row D pot quite slowly from
zero upwards
Result on my system:
In between the positions 8 AM o'clock to 2 PM o'clock of the row D
pot, the clock signal triggering the [TKB] can be clearly heard
bleeding into the signal going thru the [VCM]. Below these positions,
the [VCM]'s effect is so weak or so strong, that this bleeding can not
be heard.
Please, set up this patch and test on you system, so that I can find
peace again (whether by knowing these is something wrong, or by
knowning that this is normal).
Thanks so much in advance,
Jan-Hinnerk
