Other ideas I'd like to try:

* Envelope filter but with the expression also controlling cutoff and resonance.


How would this work? Maybe as an extra layer of hi/lo for the cutoff and resonance? So, the envelope filter normally goes from the hi/lo values you set, but the pedal lets you move between other hi/lo ranges? So, essentially, there is another dimension in the control.



My thought was I could have an envelope driven BP filter, but rock the expression toe down to have it focused on a really high range. Then sweep it back into a more bass-friendly range. Typically this would be done with a high pass filter - cuts all the low end, swept back into the slamming bass range. Typical electronica filter work, usually done with a static HPF. But I'd want to marry it to an envelope filter personally.

Or having the expression rock between two filters would do the same. Toe down for a high focused bandpass, heel down to instantly change to my envelope driven LPF.

Similar to the previous suggestion, but a little different. It'd be great to be able to Shift+Click then drag the knobs around to get a more precise gradient of control. Currently moving the knobs by increments of 1 can often be challenging.


Using the mousewheel when hovering over a pot will let you change the pot value in steps of 1, and you then also have the tactile click of the mouse wheel. This also works when hovering over menus too.


Bingo! I didn't try that.

I think this is a good idea. We'll investigate how to implement this.

This could be done, but there is usually a click when switching between band-pass and low-pass. But maybe the benefits outweight the click?

In my case I'd simply be using it to quickly switch between the 2 filters, so the stepped sound and/or click wouldn't be noticable. Play a line heel down, instantly go toe-down and play another line with a different filter. It'd be like switching presets.

Overall I'd simply like more freedom to assign the pedal to control whatever I want. It's simply a control input, let me control whatever parameters I want with it. Multiple parameters simultaneously would be great.

Again, I suggest you review any current BOSS / Roland multi-effect and review their assigns, they're robust and well thought out. You can assign any control input (envelope, LFO, pedals), setup what range the control affects, and assign it to any parameter. 8 assigns per patch. Lots of freedom with no artificial restrictions imposed.

IDEA: Allow multiple LFO to be assigned to a single filter.

This would allow some competing LFO against a single filter for more rhythmic variants, including arp-like sequences that are more designed than the random LFO. Again, look to the BOSS gear for their robust assigns. Here's two LFO assigned to a pitch shifter effect, driving a BOSS OC-2, to give a sequenced-like rhythm. http://www.cgraham.com/chris/music/bass ... io_001.mp3 You could probably do something similar with two different square LFO set to different ranges and beat divisions of the tempo, both controlling the same filter.

IDEA: Allow programmable sequenced LFO.

Check out Source Audio BEF Pro. It allows a single programmed sequence up to 16 steps to be saved to the pedal. Lets you get a very musical sequenced filter in play. Here's a sound clip I did with it last year. http://www.cgraham.com/chris/music/bass ... er_004.mp3 Real simple line on the bass, the fun is totally the sequenced and beat-synced filter.

Hye,

I'm french so sorry for my bad english...
I think the sonuus is a really good effect with almost none limits but I have 2 problems with his use. I don't know if i haven't understand something or it was a problem with the software.

First :
the pedal effect enable is a "general" parameter but it's a pity because it's sometimes useless. For example if i want to use the pedal with the option "on/off(toe)" I can't use the pedal BPM option because if the pedal is down the effect is bypassed.. I think if it's not possible the effect enable parameter to be different according the preset, we could have some additional options like the use of the footswitch and the pedal like pedal on(toe) and effect off with the footswitch for example.
Second :
I miss an option to retrigg the lfo when the effect is on! I want that the lfo start with my first note but not with the other one. If i want to have a exact tempo (without tap tempo use) it's impossible to start synchronise with the lfo.

Thank you for your response!

Yes, I agree with this and is something we have been thinking about. Already, by using two LFOs on two filters you can start to get very interesting rhythmic sounds. Extending this to have two (or more?) LFOs on each filter makes a lot of sense.

I can see the problem, but I think it will get too confusing if this can be changed on every preset?

There is already an option to turn the effect on with the pedal (toe down) then turn it off with the footswitch. In this mode, the footswitch can also turn the effect on. In the Wahoo editor, set "pedal effect enable" to "On Only". On the Wahoo itself, do the same by setting "P.En" to "on".

How would it work out which is the first note, and which are the next notes? I think there would need to be some kind of "dead time" you can set so that the retrigger cannot happen again until there has been silence for the time you set in this dead time. For example, if you set the dead time for 1 second, then you need to not play anything for 1 second to allow a retrigger to be detected again. Does that sound like it would work for you?

Yes it's not false

Yes but it was really cool to have the same option with toe hell

No i think it is most simple like you said. for example I just want to have your retrigged check box changed to an option to choose beetwen "no retrigg" or "note retrigg"or "bypass rettrigg". When the option is bypass retrigg the lfo begin when the effect is on. Actually the lfo always moove even if the effect is off when we turn on the effect the lfo can be on any position i think it is pity..

OK, so you mean to have the option to have effect turn on in the heel-down position (instead of the toe-down position), and turn it off with the footswitch?

Ok, I think I misunderstood you.

Retrigger can be turned off (it is off by default). The LFOs do free-run, but they could be reset when the effect is enabled so that they always start at the same position each time. I think this could be enabled all the time, rather than being an option. I can't think of any problems doing this -- unless someone else can?

If I understand you, let's go for me because I think it is a really good thing to do that..

Thank you very very much for your quickly and your professional spirit!!
