<DIV><FONT size=2>I have exactly the same problem. I sell the ModBox add on for
the TR606, and my</FONT></DIV>
<DIV><FONT size=2>pitch sweep circuit is based on the one from The Mix. I pulled
my hair out for 12</FONT></DIV>
<DIV><FONT size=2>hours last night trying to get it to work properly. I found
that reducing the 220ohm</FONT></DIV>
<DIV><FONT size=2>resistor to about 57ohms worked. It is a very finicky and
stupid circuit. I am going</FONT></DIV>
<DIV><FONT size=2>to try and come up with a better design, with a proper voltage
control, so that the</FONT></DIV>
<DIV><FONT size=2>bass drum can be played over a 1 octave range from a keyboard.
Imagine a 303</FONT></DIV>
<DIV><FONT size=2>sequencer playing that!</FONT></DIV>

<DIV><FONT color=#000000 size=2>Anyone on here get this part of the BD mod to
work?</FONT></DIV>
<DIV><FONT color=#000000 size=2>Mine just seems to turn the bd off when I
connect it to the hi tom trig out..</FONT></DIV>
<DIV><FONT color=#000000 size=2>I have rebuilt this part of the circuit about
3 times now, checking and rechecking..</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>I think there may be something inherently wrong with the way
its laid out, hence it being sort of an afterthought in the Mix series.
</FONT></DIV>
<DIV><FONT size=2>It seems to makes sense, but it definitely does NOT work on
mine..</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>Any answers?</FONT></DIV>
