Hi All,

I built another one. This time I wrote about tools used and some instruction for Arduino beginners

Wow, amazing!!! Just perfect!

Not all musicians have programming or soldering aptitudes, or inclination toward learning such skills.
I just have INERTIA

I just commented in Groovy's thread, I will probably pick what seem (to me) to be the best of Groovy's and Manoreken2's projects and HACK out my own.
(THANK YOU BOTH)

The THREE (or more) pedals has a LOT of APPEAL and once done it will probably motivate me to PRACTICE a lot more.

Yes, there are 8 analogue inputs on an Arduino - and pianoteq supports up to 8 pedals, SUCH a coincidence.

I've been looking at your links but I am afraid I wouldn't know how to even start putting those things together, let alone program any code...

It is not so difficult.

Just connect a pedal-poti with 5V, Ground and one of the analog inputs of the Arduino.

Connect the Arduino with a USB-cable to your PC. 

Install the software Arduino on your PC. It is free available for Linux and all other main Operating Systems.

Put my little program that I posted here in a text file and upload it to the Arduino nano hardware via USB (just one klick in the Arduino-Software).

Install an USB-to-MIDI program like 'ttymidi' or 'hairless' or others, that I don't know, on your Audio-PC.

That's basically all.

Who likes to have three (up to eight) continuous controllers for a reasonable price, could think of this:

A merge of manoreken2's code with my Arduino Nano prototype, 2 hours of work and around 10 EURO of invest:     

Jack socket, 6.3mm stereo
3 x 0.27 €

Arduino Nano
5.70 €

shrink tube
1.55 €

:-)

Certainly, There are some variety of products of pedal to USB(MIDI) converter that connect one pedal.
While, I suppose, this thread is about CME GPP-3 equivalent product (see thread title ), that have continuous input 3-pedals (sustain, sostenuto and soft pedal) like the real piano. Strangely it seems this kind of product is very rare to find

I've downloaded and tried the software, which is really nice and intuitive. Interestingly, the signal can optionally be filtered which should help with noisy/old potentiometers. The company is from Sweden and seems respectable. They've replied to me very quickly and have confirmed that they ship worldwide. I've just ordered one.

Hi groovy,

Yes, 1M resistor is there to `pull-down', to return 0V when TRS plug is not connected.

> I do not understand, what is the idea of the squareroot in your code:  float sensorSq = sqrt(sensor01);

I added a explanation of this sqrt on my blog page. Sqrt is there for pedal feeling improvement.

Ah, thank you, manoreken2!
Yes, the response of the sustain-pedal can be calibrated with pianoteq alone, nothing else needed. I did this procedure with my Roland DP-10 this morning (after using just the defaults for a few weeks).

This is my result with the calibration-assistant:

The assistant detects, that the output range of the Arduino is 0-127 and automatically suggests/sets point 1, 2, 4 and 5 in the curve.

The midpoint for half-pedalling (point 3) is a bit tricky with the assistant. I could not determine it very reproducibly with the assistant-help. So I measured the throw(?) of the Roland-pedal at the tip (26 mm) and pressed it down halfway (13 mm). The assistant then sets the midpoint to [60; 64].

It is a good idea, to finetune the midpoint further manually in pianoteq with [x; 64] for individual preference.

thnx

PS: The curve: [0, 10, 60, 117, 127; 0, 0, 64, 127, 127]

I'd built MIDI 3-pedal with continuous input using Roland RPU-3 and Arduino Uno for my Pianoteq 5.
Building converter box was relatively easy task, 1-day DIY and result is satisfying, it works perfect for me.

Hope this helps

Great work! And nice documentation!
I like the idea of the 1M-pulldown-resistors to be protected against contact-problems of the poti in the pedal. I integrated it in my Arduino Nano project today (just had to plug the resistor into the breadboard :-)

I do not understand, what is the idea of the squareroot in your code:  float sensorSq = sqrt(sensor01);

Would you please be so kind to explain it to a programming noob like me?

cheers

+1

There is definitely a market demand for this kind of product, but there is no supply. Strange!
I do not want to spend 3 to 5 hours to build another one, hope someone build and sell 3-pedal converter for you.

It "helps"

Building it may be a 1 day project for YOU, scrounging around for all the bits and pieces would take me a week or three and probably put a couple of hundred miles on a vehicle.

PLEASE post further if you intend to build a batch of these, I have a rough idea of your likely costs and respect your right to make a fair profit if you want to do this as a part time business
