Title: Does the MP-1 Chorus do Flange?
Post by: VoxG2 on January 31, 2017, 12:35:39 PM
       Just curious. It seems like I remember my old one flanging.

Uhm....maybe on some settings it could...I've to try that...

Well strictly no (but that shouldn't stop you trying  >:D ).  If you could modulate the MP-1 chorus depth (auto-magically) then it would be a flanger of sorts.
Flanging was accidentally invented by someone leaning on a tape reel while it was playing (the same signal/track) as another tape was playing it (or aspects of it), you can get this kind of thing when you have 2 multi track tape recorders playing in sync (to get extra tracks (eg 2 x 16 track = 32, loose 2 to sync = 30 tracks to record on)), lean on one spool slows it down (delay + pitch shift introduced), vary the pressure = flanging (comb filtering, out of phase waves cancel each other).
So flange parameters are pitch (freq) and pitch modulation (up/down, rate/speed) and time (delay) modulation (usually very short so waves end up out of phase with themselves and thus cancel out and modulating faster/slower).

The MP-2 chorus however does flange a bit (it has different circuit), and also I find with my slant split stack I've wired stereo, it causes some flanging as the speakers are not separated/isolated (and thus some frequency dependent out of phase cancellations).

If only the MP-1 would accept MIDI CC for that...  :facepalm:

To get a flange sound you need to have low delay times around 2-10 ms, chorus is usually higher around + 20ms.Also to get a flanger effect you also need a feedback control IMO.Now the one thing I find strange is that I own a ADA flanger pedal which sounds more like a chorus pedal to me.It doesn't flange well compared to other ADA units I have like the TFX-4 and the 2FX.

I don't like flanger that much...but I think I'll keep using the one from GMaj...  :lol:

Well you have flangers and flangers. I never liked DSP flangers like in those multi effect units like the G major and even the G force.

I have to agree with MJMP.
I don't care for the flangers in my G Force, G Major 2 or any other multi fx unit I had.  :headbanger:

  lol...I have an ADA Flanger as well. It does several things, I just want a simple swoosh flange. The chorus on the GP-8 does it, but I'm sure I'm going to use it with the MP-1. Thanks for the replies!

How flange is perceived depends on settings. I once had an Ibanez table-top flanger unit that could do delay, flange and chorus.
When it was a flange and when chorus was purely up to settings; in other words, it could just as well do a flangy chorus as a chorused flange..

Why not simply create a mod to the MP-1 chorus for adding a small amount of feedback on shallow Depth settings?
Just might result in a flangy chorus..
Turning up the Depth will gradually decrease the feedback, and it'll turn into pure chorus.
Could be done with a FET, linked to the Depth control voltage, methinks.  (but I think too much at times, so..)

Don't get me wrong guys...I owned some analog flanger pedals in the past, but I never loved that kind of effect too much, since I never found a place for it in what I play.
Generally speaking, I do not use too many effects...I prefer a dry and straight sound...just a little bit of delay and reverb and a phaser sometimes...a little amount of chorus just with clean sounds, even if now I remember why I loved the MP-1 chorus with overdriven or distorted sounds as well...

Inside units like the GMajor or the 9150, there's also too much stuff...  :lol:

Hey Max, like you I just use some short delay and reverb to taste. I haven't used a phaser in years... These are all time based Fxs (flange, chorus, delay, reverb...) it's good to understand the parameters and what they do though (eg flange delay is very short (10ms) chorus a little longer ~30 - 40 ms) etc. And as MJP said flangers typically incorporate feedback (but not the original accidental tape flange LoL).

I just calculated the delay times if someone is interested.It can sweep from 1.7ms to 34.2ms.

Post by: rnolan on February 03, 2017, 04:33:00 AM
Cool MJMP  :thumb-up: , I'm interested. So a flanger will modulate that sweep and also modulate the pitch. I suspect this works differently in bucket brigade (ala analogue MP-1 chorus) to digital implementations  :dunno: .

Post by: MarshallJMP on February 03, 2017, 08:29:30 AM
Well you have 2 digital implementations, the 80's way with RAM memory and 1 bit ADC's and the newer DSP based effects.I prefer the old fashion way with RAM memory, these also have an analog dry path.

  Ahhhh yes...like the Roland GP-8. The chorus is digital, but great!
Title: Re: Does the MP-1 Chorus do Flange?
Post by: MarshallJMP on February 07, 2017, 12:09:54 PM
Yep the GP-8 works that way.But a lot of the effects are analog except for the delay and chorus.
