UPDATE: I have received the first batch of 160!

When the total reaches 320, I’ll place another order.

Original message:

I can get the Alps N type motorized faders in the PCB mount version.  Anyone interested?

The resistance taper for these is listed as 1B.  Is that linear or log?

Is there any place that’s easy to find touch-sensitive knobs/caps for these?

I could find B, but not 1B.  That is until I clicked on the Related information (http://www3.alps.com/WebObjects/catalog.woa/E/HTML/Potentiometer/SlideMixers/RSN1M/RSN1M_common.html) link that’s on the datasheet you linked to.  1B looks to be as linear a taper as they come.

Yes, they are linear taper.  That’s the best for a motorfader with one track that is used only for control.  There are some dual track motor faders where one linear taper track is for motor control, and the second track has a log taper and the audio is passed through it…

FWIW, once SR finishes his new MF board, I hope to test the “K” model motor fader with it - if it works, I’ll go for a group buy on them too.  (RSA0K11V900C - minimum order quantity 200 - 12 week lead time - about $25 each)

I’m sorry, what makes these so special?  Do they work with the MB6582?

no, but why would you want motor faders on a synth?

dougmoser: These are perect for a MIDIbox LC.

Patch recall feature for analog CVs? Mixer feature, feedback? :wink:

well, yes :wink: I’m dreaming of 8 motor faders just as a display for monitoring the LFO end ENV states :smiley:

Does someone have experience from you to buy something from America? White exactly as with the tariff does not function completely? White someone which one for it pays?

I don’t know what other countries charge for import fees.  Where are you?  Maybe someone else from your country will know…

UPDATE: I have ordered the first batch of 160.

As soon as I know the final price, I’ll add it to the wiki.  I’ll won’t take payment until the faders are here and I know what the final shipping costs are.
