I wouldn't expect a pitch change because the inc/dec buttons just
change the delay tap without affecting the clock rate. I wasn't sure
what to expect from changing the delay tap while repeating.
- If the feedback level is set to produce multiple echoes, and you
put the unit in Repeat mode, is the recycling audio captured into the
loop, or just the incoming audio without the echoes?
*its all captured.*
As it should be.
- If the Output Mix pot is set to the Input position and you put the
unit into Repeat mode, what happens?
*dont quite understand-repeat button is saving whatever
has been captured. mix pot set to 'input' lets only the
input(dry)signal to be heard.*
The Output Mix pot should not have any affect on what is being
fed into the delay; it controls the mix between the an altered input
signal and the output of the delay. My assumption is that audio is
always being fed to the delay, so if you capture a loop while the
Output Mix is set to "Input" you will still be capturing the
incoming audio. You just won't her the looping until you move the pot
(or the remote pedal) to "Delay." PSP42 does not work this
way.
- If the Output Mix pot set in the Delay position and you capture a
loop, and you then turn the pot to the Input position, what
happens?
*your loop sound decreases incrementally as yer input
sound increases.*
Right. PSP42 does not do this. Even with the mix set to
"Input" all you hear is the loop.
- If you have already caputured audio into a loop, and the feedback
pot is set for multiple echoes, what happens when you take the unit
out of Repeat mode?
*it eventually fades over time if set at
full feedback-but it can take a LONG time.*
PSP42 does not work this way.
any more questions i can help
w/?
i have a copy of the owners manual
i can send ya-dr.
This confirms what I thought I remembered and what I could
interpret from the block diagram. I do have a copy of the PCM42 manual
(though sadly no PCM42)
looking forward to that review-where will
it appear?
This review will be on the audioMIDI.com site, probably in a
couple of weeks. I'm a regular contributor to that site (I just
finished a review of Vokator).
I'm in a bit of a quandary on PSP42, since I think it's brilliant
in most ways but "broken" with respect to these few
functions. I'd rather not make too much of deal about this in the
review, since I'd prefer it to be mostly positive. I also think that
these points could be on a "to do" list for a future
update.
Anyone who designs a software emulation of a piece of classic
hardware faces the problem of whether to slavishly copy the original
or to make "improvements" in the soft version. PSP have done
this with a couple of features, such as the clock implementation and
the way the infinite repeat works. The PCM42 would always loop the
entire contents of memory and not just what was defined by the delay
tap. Personally I never liked that. PSP42 loops the current
delay time.
