Thanks for the tips!!

Wow, 512!! :o :o I guess 1024 is not far away.. Since (if I remember reading it here somewhere in this forum that said ) MIOS can support up to 1024 switches, did anybody here in this forum actualy have implemented 1024 switches yet? If so, what application are you currently running this setup? thanks..

Moxi, When I look closely at the button on the left side, it seems like its somewhat soft, because of the bottom part of the button is bent. Are these buttons semi-soft? Or are they as hard as a rock? Also, did you polish these buttons at all? They sure look shiny 8) and perrr-ty. ;) Very nice job!!

If in case you cant find the MAX1044 or the compatible, you could make a negative 5volts voltage inverter out of a 555 timer. cheers!! :)

Or, you could use one of these babies: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1017 for your contrast voltage. thanks..

Steve, Thanks for pointing this out for me. I will investigate in that area of the code for now for the temporary fix, until I order some other encoders. thanks again.

I will find a way to video the encoders behavior later when I get a chance. Regarding how fast I'm spinning them, I'm just barely turning them (trying to feel the complete click)when all of the sudden the adjustment would go up or down a few increments. I say, I have about 0 to 7% failure rate at this moment. But before I change the settings to "DETENTED2", my encoder failure rate is about 10% to 30%. I have to turn the encoder slightly CW or CCW to get the desired note. What I was expecting is "one click turn = one increment" whether CW or CCW.. There are also times when I turn any of the encoders, that it feels that its sits in the middle of the detent, while the shaft is at rest, very annoying.. >:( That's why I need to find better quality encoders for my project. thanks..

Yes, it could be my box. I can admit to that. ;) Just to clarify things. You got me all wrong on this. I am not blamming MIOS at all. I even think MIOS is the best thing since slice bread!! ;D and TK is the MIDI god!! ;D This is just mearly a rant about the Bournes encoder itself, not the circuit design nor the applications that uses it. I just read a few links in this forum about people replacing Bournes encoders with Alps or Voti's with great results. My intention about this post is to get some inputs, to what are the best encoders out there and voice my opinion about the quality of the encoders. AFAIK, my opinion about Bournes encoder is crap!! and I'm entitled for that.. :P If nobody gives Bournes a negative feedback about their product, they will not fix it at all. Again my opinion... Whew!! I will shut up now and sit in the corner.. ;D ;D

That layout is not crap!! I can't even come close to that.. I only build my burner on a vector board.. Man, If only I have your PCB skills!! :-[ I've seen your SID-NUXX, that is one good lookin PCB. thanks

Thanks for the link.. I guess, I'm just expecting so much out of this encoders.. Before I got my Bournes, I was expecting that these encoders will behave like the ones in car radio's and such. I guess that notion is wrong.. thanks..

Nice burner!! ;)

Thanks!! I was kind'a curious about that product.

Do any of you guys (or gals, if any) know what manufacturer that makes those encoders found on those commercial instruments like Roland, Korg, Alesis, etc? The reason I ask is because. No matter how much I try to adjust the speed, wheter I use DETENTED or DETENTED2 settings, I still have some skipping problem once in a while with my Bournes encoder on my MBSEQv2. Although, I found that DETENTED2 is much stable. If I slightly bump any of the encoder, the settings gets out of whack!! >:( >:( Not very cool while in the live performance >:( >:( I'm sure other folks in this forum feels the same as me ???. A little encoder comparison: I have a Roland JV1010 module. The click feel on this instruments encoder is very pronouced, you could really feel it, unlike the Bournes. Also, I noticed that it seems like the Roland's encoder detent is much further away than the Bournes. Hence, more reliable operation without skipping. Since I'm new to this projects, I'm not sure if this is a quality problem with the Bournes encoder, or I miss another adjustments on some other files. Even so, I still think those instrument manufacturer are using better encoders that we currently use. Thanks for letting me vent out :'( :'( whew!! ;)

I see... Now you made me think of ordering the P3 as well :-\. I also like the simplistic design of it. ;)

Sorry about that. But that is why I also posted the pictures as well. For one thing, I did not cut the LED leads at all. By keeping them long it gives it a lot of flexibility. Besides the tact switch do not need to travel that much.

At first, that's the sequencer project I was planning to build. Then I saw midibox.org and this forum, that's why I build the MBSEQv2. Just wondering, why did you pick the sequentix over mbseq? thanks..

Man, that's a bummer:( My gripe about the 2x40's are, they're usually cheap looking and very hard to find. Plus no PLED version >:( >:(. Oh well ::).

I guess if we wait for the November production, the chip will have a +/- number of 0645XXX.

Here's how it looks like in action. Sorry for the blurry picture.... I was buzz'n at that moment... Mmmm Vodka!!! ;D IMG_0858.JPG

Here's another shot with and without a LED cap. The tact switch are these: http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=109034&Row=155764&Site=US IMG_0816.JPG

Those caps are the regular LED 5mm caps with notches on the sides. Here's Digikeys link: http://rocky.digikey.com/WebLib/Chicago%20Miniature/Web%20Photo/4312.jpg IMG_0814.JPG

Just FYI: I ordered the 18F4620 I/P about 2 1/2 weeks ago from MicroChip and I received a PIC with a Packaging Information number "06054R3". Pay attention on the bolded numbers. According to this PDF under Packaging Information: http://ww1.microchip.com/downloads/en/DeviceDoc/39626b.pdf This PIC was (I guess) made on the week of January 29, 2006 IMG_0862.JPG

Ok, I tried this concept, and its suprisingly nice.. I use a 5mm LED cap on top of 3mm LED and 12mm tact switch. Check it out. This is for my SEQv2/v3. enjoy.. IMG_0842.JPG

Dude, Do you know why is that the case? just curious... I read your post about this few weeks ago, but did TK specify if this is going to be a problem with SEQv3? Cuz, I would like that screen layout myself too, if its possible. ;) l8r..

Yay ;D ;D ;D Finally!! its fix!! Thanks for the info TK. I wonder if you order a sample from MicroChip, if they will give you a older version just to get rid of there defective PIC inventory.. just a thought.. So beware for the newbies..
