How to use COSM - Dynamic TVF for a Wah?

I think that the PEAK filter would work like the BPF... it's a good way of making it, but I'd like to filter my sound with LPF, using Dynamic TVF, so I can create the WahWah using the LPF. I don't know if it can be done. I think that Art could answer me this. =)
I'll try to take a look at the PEAK filter, and YES, the OD/DS should be COSM1 and the TVF COSM2 (it was good sugestion!). Resonator would not give me the heavy Wah effect in this lead (at least I think it wouldn't), but I'll try it. I don't know if you're trying to do this sound yourself, but I know that vocoder could give a good Wah-like effect (it's not what I want, I'd like to modulate it!).

The pitch bend is used for lots of things! I use it to pitch the fourth, modulation for Wah, TT for harmonics and I'm still thinking what to do with the D-Beam. I think that I'll have a good result!

Thank you for the answer!
I'll try to post a mp3 demo once I'm finished (don't expect it to be soon!).



Does anyone know how to create an Wah effect using Dynamic TVF?

Wow! Thanks a lot stealthgear!!
Yes, I was following that tutorial but it was kind of impossible with a Roland keyboard, since it doesn't allow us to use big FX chains.
I've been trying to replicate this lead for some time (since I've got my GT last month), but couldn't work with it a lot because of study/work (med school). I can't thank you enough for having this kind of work just to help me! I'll take a good look at these parameters and I'll try to replicate it in my GT. It's awsome to receive this kind of support here at RolandClan!!

"One" last question: what is the Dyn parameter? Can it be modulated by Ext In (mic or something)?? If not, can a pedal do the work for me?
I'm trying to understand what is the objective with this parameter, since I can't find a way to do a Wah-Wah with just tweaking this.

Once again, thank you!

the dyn parameter changes the filter cutoffs response to varying volume signals. that is, if you turn up DYN, then playing notes louder or softer will cause the cutoff to respond by changing values, giving the wah you want.

So you turn up DYN, then modulate the volume of the signal going in with whichever controller you deisre!

also, yes, an expression pedal will definately do the trick, though i seem to remember the menu to set up pedals to do something other than volume/ note hold is a bit hard to find!

edit* i am using v-synth keyboard NON-GT. the dyn behaviour should be the same. not sure about pedal control!

Thank you timetripbeatkeep! This is what I wanted to know!! =D
I could also modulate OSC TVA Sustain the get this result if it is what I understood. It's a great info for me. I'll try to get some results with this. With the help of stealthgear I've got some conving Wah sounds... it's funny how the V-Synth's TVF are better than the Auto-Wah effect. It's good because I can still use the FX with something else.

Once again, thanks for the info.

Finally got it right!!
Got a great resulting sound this morning, with just 2 Osc (basic sound... needs another one for creating a good feedback layer). To the one interested in this thing, I'll put some parameters so you can do it as you like.

General: Mono with or without legato/-12 and +2 in pitchbend/Lots of controls for COSM1 Cutoff and Resonance (modulation) for example and some other for Osc volume for creating the feedback effect (aftertouch - need another Osc...for GT users only, sorry!).
Osc 1: LA Saw
Osc2: LA Square/tweak Pulse Width
COSM1: TVF - BPF/tweak Cutoff/High Resonance (not highest!)/If you want you can add a very little decay to the cutoff envelope to add some punch to the attack...
COSM2: Amp
Effects:
Hexa Chorus: This one is essential to the basic sound! Adds a HUGE power to the sound... can't be done with the basic chorus effect.
Chorus: OFF
Reverb: Delay
There are some refinements that need to be done in ALL EQs, but it's just basically a bass boost. =)

I hope this helps everyone trying to achieve something like this sound on a Roland keyboard. It was very hard to get a result as I wanted, but I finally made it! I'm not posting this yet, it's not entirely done... I'll give you an audio example in the future.

In the end, I managed to use Korg Legacy Cell for making the sound, and then "translated" it to the V-Synth GT. The Wah effect was the main problem (in Korg there's a GREAT Wah-OD-Gain algorithm) but managed to make it with filter tweaking (the Dinamic TVF wasn't very helpfull).

Thank you guys for your help!

Still working on the feedback layer so it isn't demonstrated! =D

Awesome sound! I like it, thank you, Igor.
