Crossfade faders?

Has anyone found long (80-100mm) easy gliding faders to use as crossfaders?  10k, linear, dual-pot would be ideal.  I see a lot of projects have horizontal faders, but I’m wondering if anyone found faders that have that right feel?

ALPS Faders are certainly ideal for all audio apps. Theyre the most easy to move faders I came along up to now.

Theyre also available as dual-pots, also I´m wondering why you would need that for an MBHP/MIOS App?

In theory, I guess you wouldn’t, but as I understand it, on  faders (as opposed to pots) the dual pot works in opposite directions.  Emulating the crossfader in a DJ mixer.  

A----[llll]-----B

moving the slider left brings up channel A, while dropping channel B.  and Vice Versa.  

This may be based on a fantasy, but it seems to make sense, doesn’t it?

Yes, it is, and if you build an *analogue* mixer, you really do need that. Many high quality mixers (Omnitronic for example) in fact do use ALPS dual faders.

But if you build this thing for digital (MIDI) apps (e.g. Traktor Mixer) only normal pots are needed, the mixing is done digitally.

In the firmware, or the software?

Software that is controlled via MIDI input (If I understand your question correctly)

You would program the “Firmware”(MIOS App) to route the fader’s position to a midi event suitible for your software to interpret.

Many thanks.
