diamond memory lane - how does the modulation feature work?

[ulysses]

hey guys

can someone explain to be in simple terms how the modulation feature of the diamond memory lane works..

it sounds like a really nice feature.

how hard would it be to work in this feature to a reboot 2.5 from tonepad?

cheers

look's just like an LFO hooked up to control the delay length

you could do this with a LDR hooked onto the existing potentiometer thats hooked onto pin#5 of the PT2399
or heres how do do with any control voltage and a regular transistor: http://sdiy.org/destrukto/vc-echo.html

so i presume the lfo is tempo timed to the delay repeats. does this sound right or am i completly off track?

so basically that modulation video on the diamond memory lane webpgae is just the tempo knob being increased and decreased by an lfo? am i on the right track??

so esentially could i do this by manually changing the position of the delay knob?

to get the type of effect that is on the video at the diamond memory lane site, i presume the lfo would have to be very fast. is this correct or am i way off track here

as per my previous post, would it be possible to tie the lfo tempo in with the delay time. ie, have a switch so the lfo speed twice the delay time? or 100times for that matter?

do you mean pin#6? pin#5 appears to be NC??

looking at the modulation controls on the memory lane, there are two knobs, speed and depth.

if the modulaiton is just an lfo controlled delay speed adjustment, does that mean that the depth knob would be a lfo waveform adjustor?

err, yeah pin #6, sorry was working from memory, only one pin off

nope, the modulation LFO is completely independant

yep, the modulation works by moving delay time by a tiny bit, giving it that chorusy sound (this is just how chorus pedal or flanger works )

looking at the modulation controls on the memory lane, there are two knobs, speed and depth.

modulation speed = how fast the LFO that effects the delay time is LFO-ing
modulation depth = how much it changes the delay time (eg: "from +0 to +10ms over the base delay time or from 0 to +30ms")


so esentially could i do this by manually changing the position of the delay knob?
you could probably do this by hand but it'd probably be way way to much of change in the delay time and it'd probably come out sounding a bit over the top (just mess around with the delay time of any delay pedal while playing to see what happen  )

the modulation LFO isn't that fast, it seems to be like any other LFO you'd find in a chorus/flanger/phaser pedal

as per my previous post, would it be possible to tie the lfo tempo in with the delay time. ie, have a switch so the lfo speed twice the delay time? or 100times for that matter?
I'm pretty sure it would be possible, but it wouldn't be simple (espescially with the Rebote)

cool man thanks for your reply
