hi all,
I built the pt2395 delay on a breadboard last night. After a few hours I
got it to work, but it seems like I've got something wrong still.
I'm using a vco from a 4046 PLL as the clock so I could get voltage
control but, it seems to change the pitch of anything that has already
went into the delay if I change the clock speed before it's echoed back
out. Is this to be expected? If so, then I don't see why voltage control
would be all that useful?
also, the output seems to be a lowpass filtered version of the input
with a fairly low cutoff frequency. I'm loosing all the higher
frequencies. The input and output sound exact if I filter the input and
put my oakley multiladder cutoff at about 1/4 of it's range. Sorry, I
don't know what frequency that would be. Is this what it does, or did I
do something wrong?
has anyone else built this module? I'd like to hear what other people
are doing.
