No Memory - Spill the beans! (UPDATE PAGE 7)

[Jwar]

I made two more demos. Going to work on uploading them.

super quick clip with an EHX big muff > no memory showing off it's super rad pitch-bending capabilities.

How'd the delay time drift test/dinner go Brian?

How'd the delay time drift test/dinner go Brian?

no drift. when i was testing originally on the breadboard, i ran the same chip for about a week straight without unplugging it and never heard anything unintended. i think tomorrow while i'm building though, i'll let a loop run through a no memory for a few hours and listen for changes.

[goroth]

Good to hear. And dinner was ok?

[goosekevin]

I'm so mad at myself for not buying one of these
Excellent pedal dude!

[Eivind August]

Hm, will play it more today, then. Worst case scenario: Something is broken inside, and I'll have to ship it back and play the waiting game for yet another few weeks. Best case scenario: My playing has transcended to the point were I break the limit of time and space.

Edit: Think something is wrong in the land of Memories. Sent you an email, Brian.

[goroth]

The delay time does change depending on how you set other stuff, and I've noticed it can get "stuck" when changing parameters sometimes, but if you put the time put to zero and bring it back up it goes back to normal. But mine definitely doesn't drift.

[UglyCasanova]

If you turn the time knob clockwise when both the range and bend knobs are on higher settings (perhaps even some strange lag/sweep toggle combo) it will give the impression of changing the delay time over a longer period of time. But it does "set" in the end. At least in my 30 minutes messing with it, trying to get what Eivind is experiencing.

[Eivind August]

Well, mine will change suddenly, and quite dramatically. It also changes delay time when I engage modulation

Also, I know it's supposed to be a bit noisey, but mine seems to have a bit of weird feedback going constantly, even on short delay. If I turn the range knob fully counter clockwise, it's more faint and high pitched, with range around noon, it's quite noticeable, again even on short delay settings.

I dunno, I might still have alot to learn with this pedal, but it seems strange.

EDIT: Uglycasanova was kind enough to do some short clips were he tried to replicate the "problems" described above. So I guess it's supposed to change delaytime when mod is engaged. I can live with that, will probably have mod on most of the time anyway. Will try to get rid of the feedback by trying different outlets around the house. The sudden, unprovoked changes in delay time and noise might be due to incompetence on my part

Sorry if I scared anyone, I still think it's an awesome pedal. I just need to find out how to deal with its idiosyncrasies.

[goroth]

Yep, delay time changes when you engage the mod. It's modulating the delay line to produce pitch modulation, not adding a separate chorus or vibe effect. The range knob affects both the modulation and also the total delay time (correct me if I'm wrong Brian!). It's a bit of work finding a sweet spot with a cool modulated sound and a cool unmodulated sound.

Re noise: a pt2399 delay chip is only clean up to around 300 ms, 500 with some filtering. Given that the no memory can do 3000 ms of delay (and more depending on the range knob) there's going to be a lot of white noise for most of the travel on the time pot.

Not saying yours isn't messed up! Just documenting some thoughts that may or may not be relevant.

It's definitely the weirdest pedal I've played and I freaking love it!
Brian - when in non modulated mode maxing the range knob shortens the max delay time, while in modulated mode maxing the range knob pushes out the delay time to... cray cray levels. Haven't measured.
Yes?

Trying to work out the effect of the lag switch as well.

Super fun. It's like a Rubik's cube of delay sounds.

[Eivind August]

Good news everyone!



I'm pretty sure it's not a faulty pedal. The noise didn't get better in other outlets; it got worse. Which probably means the electricity here kinda sucks, and the No Memory is sensitive to it. Found some sweet spots were it wasn't noticable while playing. It does do some weird stuff, but with certain settings it was quite... controllable?

I still have no idea why it randomly changes delaytime at some points, but it seems to only happen on certain settings, and only when modulation is off. I might have found the flux capasitor or something. Anyway, it's an awesome pedal once I got it dialed in. Very sensitive knobs. Also, I noticed that the envelope filter on the mod (?) needs to be pushed harder when I run fuzz into it - not as sensitive as when played clean.

tl;dr: I think I might be a noob

[smallsnd/bigsnd]

yeah so it still shouldn't be doing that. i will keep investigating. perhaps the PT2399 in there is acting a little strange?
to add notes about the controls:

- yes the delay time *can* change when turning on modulation, but not always. it depends on where the range is set - higher range settings will likely make it jump more.
- re: noise. there is an unwieldy amount of delay time available, from 30ms to 3000ms, to around 8000ms with the range knob being used and anything over 500-600ms will have some digital noise. also, with the EQ pot fully CW there is *less* filtering than on most PT2399 designs so the noise will be even more apparent. bringing the EQ knob to around 2 o'clock will cut most of the noise up to around 1sec and at noon will cut most of the noise up to around 3sec - obviously your instrument/amp settings may change that slightly.
- LAG - this is slightly mis-labeled as 2 (left) is the longest lag, 1 (center) is no lag and 3 (right) is in the middle. (sorry!) the way the lag works is two-fold and you can think of it sort of like a "glide" or "portamento" control on an synth. if you're unfamiliar with those, then here's what's happening: when lag is engaged, the time knob will not immediately change the delay time - there will be a lag until it "catches up" - kind of like some tape delays as well. when using modulation, this creates for slower/longer pitch shifts that are not as drastic.
- re: fuzz and the envelope control - that's exactly right. when using fuzz, the envelope control will be less sensitive since your signal has been squashed and turned into a much more square signal with less dynamic information.

also, one other quick note on "latching up" - if you turn both the range and time knobs CW, most of the way then the delay *may* "latch up" and seem to get stuck, though this doesn't happen every time. to remedy this simply turn BOTH knobs CCW, though you may be able to unlatch it by turning only the range knob.

[Eivind August]

yeah so it still shouldn't be doing that. i will keep investigating. perhaps the PT2399 in there is acting a little strange?

Probably not, but since I was able to avoid it with some dialing, I think it's ok. Having a time travelling delay is pretty cool, as long as it doesn't happen out of the blue on every setting.

Thanks for sharing some info on the controls, will come in handy.

Man I'm anxious. Jwar demo was crucial. Love the noises in the box. Does it come with a manual?
