rambinator Posted November 22, 2004 Report Share Posted November 22, 2004 Hi!As I am using a yamaha clavinova as a midi-keyboard I don't have a modwheel or pitchbend. I am know progressing with my midi box and I asked myself if it would be possible to integrate some wheels in the box but I couldn't figure out how to do this mechanically and I didn't find any spare parts on the web either...Has anybody allready realized something like that?cheers,rambinator Quote Link to comment Share on other sites More sharing options...
goyousalukis Posted November 23, 2004 Report Share Posted November 23, 2004 Well, I don't know if you will find new replacement Mod wheels easilly, but you have a couple of options. Try to find a dead keyboard to steal one from. Also you might consider using a Joystick like some manufacturers do. I found a couple of old Apple IIe joysticks at a flea market for $1 apiece, and they worked great. You can also use them for things like filters as well.Justinp.s. the great thing about the joysticks I got was that it had mechanical switches to change it between auto-centering and loose.

Guest kostix Posted November 23, 2004 Report Share Posted November 23, 2004 if u would make them yourself, i think you could do something like this to get an effect like that:i would take the potentiometer, and drill a hole in the rod perpendicularily to the rod. then fix inside of the hole a piece of some strong wire/cable/whatever or something to make a "T" or a "+". then i would fix the pot to some surface, with its rod parallel to the surface. after that u gotta find a couple of equal springs and fix each to the strong wire's both ends. the other ends of the springs u fix to the surface below.i guess u would have to calculate by hand and eye how high you put the pot above the surface , and this way both springs will be pulling the wire letting rod in this "springy" state hehealso when drilling the hole, make sure that the pot is at its middle position ..thats it :) Quote Link to comment Share on other sites More sharing options...
rambinator Posted November 23, 2004 Author Report Share Posted November 23, 2004 Thanks a lot for your replies....@kostix: I allready thought about something like that myself, I guess thats how it works in the commercial ones... but I didn't try it yet because my father who is a mechanical engineer quite skilled in craft things laughed at me and said I wouldn get it to center at the correct position where I need it to be for the original note, because the pot doesn't have a detention at that position. But maybe I'll give it a try anyway.@goyousalukis: That sound like it is worth playing around with. I should have an old joystick somewhere. Also the use for filters you're proposing seems interesting.cheersrambinator Quote Link to comment Share on other sites More sharing options...
ryan.shuck Posted October 6, 2005 Report Share Posted October 6, 2005 Doepfer sells single (10Euro) and dual (30Euro) modwheels with removable spring return. http://www.doepfer.de Quote Link to comment Share on other sites More sharing options...
SMIDIRIN Posted October 8, 2005 Report Share Posted October 8, 2005 the "Some Random Thoughts About a Modulation Wheel" page perhaps ..http://musicfromouterspace.com/analogsynth/ModulationWheel/ModulationWheel.htmlyou could make rows of these.

rambinator Posted October 13, 2005 Author Report Share Posted October 13, 2005 Not bad this idea.But as far as I understand, this is just an endless rotary encoder, based on optical elements, just like in a mechanical computer-mouse.It wouldn't provide the tactile properties of a modwheel, which goes back automatically to the zero-position etc...

illogik Posted October 13, 2005 Report Share Posted October 13, 2005 HiBut as far as I understand, this is just an endless rotary encoder, based on optical elements, just like in a mechanical computer-mouse.not exactly, this is more like vactrol control: the light which falls on the photocell is changing it's resistance (you don't get steps). I've been experimenting with vactrols and IMO they sound wicked, as long as you don't get light from the surroundings they are pretty stable (so you could get nice center position as long as you get it right with the springs) and have a real analog feel/sound to them(read: they are not as quick as some other controls so you can hear it going to a stable value). haven't used them in controllers though so this might be totally differentlet us know if you try it out cheers, marcel Quote Link to comment Share on other sites More sharing options...
