Guest echelon Posted October 28, 2003 Report Share Posted October 28, 2003 Hi everybody,I'm looking for push buttons who return to the 'open position' after I push and release them. How do you call these type of buttons?I want to choose between 20 different buttons but a midi signal is sent only when pushed (note on) but I do not want to push a button twice to have it returned to it's begin state. I've looked at some buttons but all off them work with a 'click on' and 'click off' system. Can somebody give me advice on this? ;DDoes Reichelt have these kind of buttons? Or do I have to look somewhere else?Thanx for helping me out.greetings Echelon Quote Link to comment Share on other sites More sharing options...
Nat Posted October 29, 2003 Report Share Posted October 29, 2003 This is usually selected in software or in mios... You can have normal push buttons and transform them in toggle switchs via software/mios... Quote Link to comment Share on other sites More sharing options...
moebius Posted October 29, 2003 Report Share Posted October 29, 2003 Hi!I think you are meaning the button (or switch) type. Those are normally referred as momentary (mom) type. And buttons should be normally open and closed when pushed (OFF-ON). You can of course use ON-ON type buttons, but then you have to check the wiring so pressing it will close the contact.Samppa Quote Link to comment Share on other sites More sharing options...
pay_c Posted October 29, 2003 Report Share Posted October 29, 2003 Good & cheap (although a little small for some people): Taster 3301D (and the other types) @ www.reichelt.de~0,15 Euros the piece Quote Link to comment Share on other sites More sharing options...
Nomical Posted October 30, 2003 Report Share Posted October 30, 2003 They are also called SPNO switches/buttons, which stands for Single Push Normally Open. Quote Link to comment Share on other sites More sharing options...
Guest echelon Posted October 30, 2003 Report Share Posted October 30, 2003 Thank you guys for you're fast response.You've helped me a lot and I'm already looking for them.One more thing:I want to connect momentary buttons to a DIN module and leds to a DOUT. When I push a mom button a corresponding led should light up. When I release the button does the corresponding led go to the 'off state' as well?If the led should turn 'off' after releasing the momentary button is it somehow possible to keep the leds 'on' until I push another button in a same group of buttons?Let's say DIN connectors 1-18 are one group. So when I switch from one button to another the led will follow this action. In this way I can see which button I've pressed the last time.Can somebody give me advice on this one?Thanx Quote Link to comment Share on other sites More sharing options...
TK. Posted November 1, 2003 Report Share Posted November 1, 2003 You mean a "radiobutton" function. Something like this can be realized by using Meta events (MIDIbox64, 64E, MF, NG) - requires programming skills. It's also already used by more specific applications like MIDIbox LC and MIDIbox SID.

Nat Posted November 1, 2003 Report Share Posted November 1, 2003 64E ?Could this mean the 16E will support more encoders when ported to MIOS ? Quote Link to comment Share on other sites More sharing options...
TK. Posted November 1, 2003 Report Share Posted November 1, 2003 Sure! :)Excerpt from the ChangeLog o biggest improvement: MIDIbox64E can handle with up to 64 rotary encoders and LEDrings! o all 128 encoder and 64 button entries stored in a bank can be updated by incoming MIDI events o the previous "subbank" mechanism which divided the 128 encoder entries into 8 "banks within banks" has been renamed to "pages" The width of a page is free definable. This means, that all 128 encoder entries can be controlled by MB64E with a single encoder (low-cost solution) as well as with up to 64 encoders! Best Regards, Thorsten.

Nat Posted November 1, 2003 Report Share Posted November 1, 2003 damn, the price of my box will double now :PIf I understand the "page" system well, this means that with let's say 16 encoders, it is possible to control 128 parameters within the same bank ?

TK. Posted November 1, 2003 Report Share Posted November 1, 2003 Yes - but this was also possible with the PIC16F based version. The new feature is, that all these 128 parameters can be received independent from the selected page, the PIC16F was only able to receive the 16 parameters of the selected "subbank".In fact this means that 128 virtual knobs are available, and it depends on your hardware how much can be controlled without switching to another page.With 16 encoders I highly recomment 8 additional buttons which should be assigned to the "Select Page" function, so that you can quickly change between the different views.Best Regards, Thorsten.

Nat Posted November 2, 2003 Report Share Posted November 2, 2003 How much physical buttons are supported ? I planned on 64 buttons. Quote Link to comment Share on other sites More sharing options...
TK. Posted November 2, 2003 Report Share Posted November 2, 2003 128 inputs. With 64 buttons you've 64 remaining inputs for up to 32 rotary encoders.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Nat Posted November 2, 2003 Report Share Posted November 2, 2003 Thorsten, I just want to say how much I'm impressed with the midiboxes, there is no commerical surfaces that come close to what MIOS can do.Thanks for making all of this possible :) Quote Link to comment Share on other sites More sharing options...
