  1. Le code est maintenant sur github https://github.com/jerash/PedalSwitcher
  2. Oh si il est polyphonique ! Tu as 8 voies simultanées que tu peux router vers un canal/port midi dédié ! - Yes it it polyphonic, you have 8 simultaneous voices you can route on a dedicated midi channel/port !
  3. Hello, back in 2013, when I had spare time for personal project I built a guitar pedal switcher for the bassist in our band with MIOS on the PIC18f. It has been rapidly discussed in french here, and used without issues for about two years on stage in his pedalboard. With the current version it has the following features : Midi In/out/through LCD display with menu for options and presets 8 relays with either switched or momentary state 4 menu buttons, 8 relay command buttons with LED indicator 100 user presets with midi recall 4 programmable quick access buttons (footswitch recall preset) with LED indicator grouping (radio mode) of relay buttons is possible You can see pictures on the unit on this album, and code with some infos can be downloaded from the post I thought about updating the wiki page with my built, and never effectively did it. Today I'm running a musical instruments repair business (www.audiotronic.fr), and doing builds on user request. I've been asked to design a similar system for a new french company willing to build pedalboard with integrated switcher system, and when I showed him my build he found the design of the system to be simple and effective and would like something very similar. So here I have two options : use the existing midibox code as a start (hence this request), or redo the thing from scratch on another system. There will be no secrets in the coding of this switcher, so I'd feel comfortable in sharing the updates in the code, while not mentioning the final product name publicly would make sense. I've not been an very active user in the midibox community, so let me know how you feel about this. Raphaël
  4. Hello, I have a stock of EPROMs I won't use anymore. Before they're all gone for sale on ebay, I'd be happy to trade some for midibox parts. i'm interested in Especially a LPC17 board and parts (including LPCXPRESSO), or a MB_NG board and parts. here's what I have : 27c512 qte 57 : 512K , 64K x 8 bits 27c256 qte 12 : 256K , 32K x 8 bits 27c010a qte 48 -10hs : 1Mbit , 128K x 8 bits 27c2001 qte 183 : 1Mbit , 128K x 8 bits 27c1001 qte 63 : 1Mbit , 128K x 8 bits 27c020 qte 53 : 2Mbit , 256K x 8 bits If you have what i want and you won't use it, or have any other idea, let me know. I live in France, south south....
  5. ok C_04 i've got you PM
  6. Look like you have many projects going on. Be careful of the weight. Those little beasts are becoming heavy when numerous…depends on your budget. If you want many of them, i'll have to go for a packet instead of an envelope and the price is not the same (minimum 16€ for 1Kg maximum, 25€ for 5Kg). Here are the detailed references I have, on the right is the maximum quantity i can offer for one person. Please pick a selection, and send me a message. Eprom 27c512 qty 15 27c256 qte 5 27c010a qte 10 27c2001 qte 20 27c1001 qte 10 27c020 qte 10 SRAM Samsung K6T4008C1B qte 20 Japan SRM20100LC70 qte 2 M5M51008BP qte 2
  7. hello, depending on how many you want price may vary. A dozen units would cost around 5€ in international simple letter I think. Tell me how many you want and i can tell you a more precise price. These are not intended to be for resale, but for personal projects.
  8. voici la version actuelle du code source pour le programme du pedal looper. Encore quelques améliorations à apporter, dont certaines sont documentées dans le fichier specification.rtf qui n'est pas forcément très à jour. les remarques sont les bienvenues ! to be continued.... PedalSwitcher.zip
  9. Hello, my employement company is destocking, i have an opportunity to have a lot fo EPROM for free : 27C010 27C020 27C512 from ST microelectronics, more than 100 units of each reference. and also SRAM chips Let me know rapidly if you are interested, so i decide to take them home or not. I will send them for postage costs only (shipping from FRANCE) until i have enough spare enveloppes to send them. Raphaël

    I've read a lot of information from various website projects before choosing. A lot of information came from a french collaborative project of www.techniguitare.fr They made a similar project from wich i inspired, and adapted it to the midibox and add some features like buttons switching, and grouping...(to be detailed) I'm using Omron G5V-2 for audio switching and G5V-1 for relays/buttons switching. They are driven by an ULN2803 for efficient switching. These relays have been proven to work great on audio switching by the users who built the above mentioned project. So after building it myself i can confirm : The relays do work silently ! Most of the audio clicks come from the pedals themselves when they are connected to the audio path. So it is important to verify, especially for non-buffered pedal (true bypass), that it exist some resistor on the input to absorb the generated clicks. I had problems with a EHX mini Qtron and I had to modify it. All other buffered pedal worked without problem for me. Also from what i've read and understood the ULN2803 (see the picture of relays board in this album) is giving the relay a kind of voltage boost when switching to guarantee fast transistion, and thus less rebound. Too much boost would shorten the relay life, just enough would help. I'm sure that many highly priced commercial products do use the same mechanism. As all drawing I've seen to reduce these noises, are acting on how the relay need to switch, I don't know about any other improvement "after" the relay.
  11. OK thanks for the reply, i get the scheme for coding it... if my skills are able to do it :sheep: I just wonder if we can handle the interrupts directly with MIOS already "installed", need further investigation !

    hey, thanks ! It works really well, i'm also happy with the menu handling on the LCD. I've added a relay board with ULN2803, which need documentation. For me MIDI is very usefull because I mostly command the pedalboard with automations from Ableton Live. The footswitches are only use when practising new songs ;) I'll soon share my code project based on MIOS.
