Hi,
I'm a newbee in the arduino world... The lawrence midi controller will be my first realization.
So... are there any different USB shields avalaibable for this project? If I choose one of them, will it work?
Thanks!

Damn! Recently received the Keyes shield... but as 0-level beginner in arduinno stuff, it doesn't work (waht I knew it certainly happen ).
Well, foudn't te keyes library here

Hi Lawrence, My work is in progress: I just didn't understood how libraries work with arduino.
This work is my first project with this stuff... Hard but very instructive!
The library works fine now, and the program is compiled... So I think it's just a wiring problem.
I 'll give you some news later... when it works!

Waaaaaaaaaaouh! It works!!!
Perfect is the real term: things talk together! Just like with your youtube post!
I have no DPDT switch to wire S6 yet, so I haven't wired L6 & L7 (just use a connector to simulate S6).
Just few questions:
- L6 & L7 are directly wired to VCC: Isn't it a problem? (should have put a resistor like R6+L1...)
- DPDT switch for S6: If I understand: it is used only to power L6 or L7. Why haven't you used logic on digital 6, to supply Analog 4 (to L6 for example) or analog 5 (to L7)? I/O standard switch would have done the job.
- Programs affected by switch, on the zoom are: 42, 43, 44, 48, and with bank B: 45,46,49,50 - 47 is for Bypass... Is it possible to change those values to another ones?
I know you have other projects Lawrence, I would like to thank you alot for the work you have done, and more: for having it shared with others.
Congratulations, and many thanks for your work!

OK, I've got another Idea: instead of using a DPDT switch to use only 2 channels, I think it must be possible to use a midi pedalbord to configure which channel use. I saw a midi library in the list used in Lawrence script, so...

(should have put a resistor like R6+L1...) YES - You are right... it needs to have a basic small resistor - same as R6 / 7 / 8- DPDT switch for S6: If I understand: it is used only to power L6 or L7. Why haven't you used logic on digital 6, to supply Analog 4 (to L6 for example) or analog 5 (to L7)? I/O standard switch would have done the job. DPDT switch not only powers L6 and L7 it sets Digital 6 - HIGH / LOW and you need that to determine the next set of patches in the next bank- Programs affected by switch, on the zoom are: 42, 43, 44, 48, and with bank B: 45,46,49,50 - 47 is for Bypass...

Hi 777 funk, Hi Lawrence, sorry for the delay: You made the effort to answer fast... So didn't do I!!! As a midi switcher, I thought about that: www.youtube.com/watch?v=F3r-vl1_wcs&spfreload=5Tech 21 midi mouse. Pretty little box, to keep the interest of using a little MS70CDR stomp. (Instead, you'd better buy a big multieffect with tons of pedals & effects...) So Lawrence: more explanation about my idea: If I have correctly understood your project, we have access to only 2 channels, switched with DPDT. Instead of that, I propose to use a midi switcher, to access to more than 2 banks. For example: - 1 on the midi switcher give programs 11,12,13,14 - 2 give 21,22,23,24 - 3... Unfortunatly my knowledge in programing are... antedelivian, so I have difficulties to understand arduino programming. However, I understood that libraries are needed... and a midi library is called in your program. So It must'nt be very difficult to translate midi in form external midi switcher, to change the midi bank. Replace DPDT with standard switch (cheaper)..., or put a little switcher to a have both functions: standalone or with midi program change... That's my idea. A bit unclear, I agree... |

Hubert,
What I have done is an advanced version of the Tech 21 MIDI mouse...
What MIDI mouse has done is simply increment or decrement the patch.. it is too simple to be done.
I have limited to 2 channels is because I need only 8 patches... and if you need more it can be done, without using using a midi switcher. All you would need is two switches that are labelled as UP and DOWN... and you can switch banks up and down between 1 - 25 if you need.
Regards,
Lawrence

Hi, I am newbie too, and my English is not so good, My question is, I have a Arduino UNO, i can control the ZOOM 70CDR with the USB port of the Arduino, or I need a USB shield? Thank you |

No Marcel.. you would need a USB shield. It would take a long time to explain why |

I'm planning a build of this project, but don't have much experience with Arduino and serial/USB communication.
What I get from your statement above is that an Arduino's Tx/Rx pins CAN NOT be used to send messages to a zoom pedal?
