Yo. And maybe have someway of determining the mininmaum and maximum of this, so like when you start it begins at a preset amount and only increases to a preset amount.
Vibrato, noise, compression and adjustable momentary bit reduction.
if any of you were wondering heres what I'm tentatively thinking for potentiometer controls:
Tape Speed
Tape stability (depth)
bit crush (with momentary footswitch)
Hi pass
Low pass
Noise
blend
I was considering doing a compression control but I feel having compression on all the time is better because it allows for more tweakability of the more interesting parameters.

Maybe a trimpot?
a more likely solution will probably be a switch...the reason for this being there are only three potentiometer inputs on the spin fv-1 (i will be using two fv-1's for this pedal, a total of 6 digital controls) and I think the other controls I listed above have a larger impact on the overall sound of the pedal.
like I said Im still considering the options here. have the pcb all ready and am just working on the code

Yeah compression is ALWAYS fine for this kinda shit
"The recorded frequency range was dependent on the linear tape speed. For the VHS SP mode, which already uses a lower tape speed than the compact cassette, this resulted in a mediocre frequency response of roughly 100 Hz to 10 kHz for NTSC; frequency response for PAL VHS with its lower standard tape speed was somewhat worse. The signal-to-noise ratio (SNR) was an acceptable 42 dB. Both parameters degraded significantly with VHS's longer play modes, with EP/NTSC frequency response peaking at 4 kHz."
I think it's this, plus poor tracking simulation via random LFO on pitch, some overdrive (your audio blasted through big a plastic Magnavox enclosure), a high noise floor and probably an analog compander like the one in Boss DD-3.
Good deals with PumpkinPieces, hazelwould, PetZounds, Steelyeye, DannDubbleEwe (x3), skullservant (x3), ChetMagongalo, leaves turn, Helter, EvilCatBucky, OddKnowledge, vanderholm, Phengren Oswald, Uncle Grandfather, decomposing, MrNovember, multi_s (x2), smallsoundbigsound (x2), Dandolin, Strangle Tales who is a good dude
ive spent far too much time reading that wiki already! its really interesting stuff. I feel like the bit crushing may not be true to vhs audio degredation but it is really part of the vibe im going for in this pedal. the pedal is really influenced by neon indian's halogen

The frequency response of the average guitar speaker has way less bandwidth than a vhs.
Good call on the dd3 compander!

That’s quarter-assed at best.
I guess I'm selfishly not considering guitar at all, so having a fixed low bitrate might make sense in order to simulate the limited bandwidth. Like 12bit?

Can you add a wild kind of chorus as the first effect in the signal chain in FV-1? Seems like that would fit the opening to the reference clip. So it's like Chorus-y delay > Bit Reduction > VHS Filter /EQ (moreover, to clean up the sharp edges from the reduction) > Pitch LFO > Compander?
I've never looked at FV-1 programs but I'm guessing they can at least theoretically run like this.
