I would think you could map the very same effects to the touchstrip of the twitch only with more precision as they both send a message when touched and released to trigger an effect on/off, but only the twitch can send absolute messages so you can press anywhere in the touchstrip and activate the effect or chain of effects at that intensity, with a jog wheel you’re at the mercy of an absolute encoder which can only gradually increase or decrease a parameter in software, and if you use modifiers the sliders you are controlling, the effect sliders move relatively so will not move back to where you started. plus on the twitch you have more buttons that you can use to shift the action of the touchstrip. and Two leds giving three colors of the grid for an easy way to tell what shift is enabled.
The only limit is traktors 8 modifiers, so you would probably have to shift the touchpad with the grid below it, still it would be better if traktor had at least 4 more modifiers to play with…
the only other thing twitch is lacking is the extra 4 effects knobs, but it is rare you would find yourself wanting to use two effects units at the same time, although there goes 2 more modifiers to shift the effect unit which leaves you only 6 to shift the touchpad. which you wouldn’t want to use them all for…
Also twitch comes with itch so would make it cheaper for the upgrade if/when serato opens up… But best of all It has been mapped by a user to VDJ Pro in full HID so you could really make it do some amazing things not possible in itch or traktor with some clever mapping as there are no software restrictions holding your imagination back, and much more control over the way you are mapping.
Also just found out that twitch has 2 modes for the touchstrip, absolute and relative (like a jog/endless encoder) I kind of want one now LOL, if only the faders weren’t plasticy feeling and the crossfader was better it would be a perfect edition to my turntables… Oh well twitch 2.0 might be better if they ever make one or get a miinnofader to fit
