Hi - I adapted the Pedalshield (as developed by Electrosmash) code and they used switches instead of a potentiometer. It will be possible to add a pot to change the delay but I am currently not doing any work on this project.

Hi as I mentioned in the parts list the TL872 will be fine.

HiI used an empty external 2.5" drive housing, opend it and took out the PCB inside

HiIt has been a long time since I worked with the VS1053 boards but if I remember correctly one of them only brought out one of the two lines for connection to the outside. In addition their code that they supply with their IDE only did a DSP on the Line1 input which is the Mic input. I do not remember any lag...

Do you have a schematic or connection diagram perhaps?

Thanks!

HiYes you can use an lcd but you will have to change to code to suit the characteristics of your LCDSearch for the link to an instructable that replace the rotary encoder with a potentiometer: USB VOLUME CONTROLLER - POTENTIOMETER BASEDI am not sure which of the 5:1 speaker configurations can be controlled via the USB HID's - you will have to search for more information.

Ok if I understand your setup correctly you changed two things - the display and the Arduino is not an Uno but a Mega?You can try this:Connect the output of the 6N138 via the 220 ohm resistor directly to the VS10563 RX and disconnect the Mega TX from the RX of the VS1053Make sure your keyboard is transmitting on midi channel 0 and see if you get any audio output - if the VS1053 is in the correct real-time midi mode it will work without the mega sending it midi notes. You still need the mega in the beginning to load the VS1053 real-time midi code though Are you using the Adafruit VS1053 board?Use the email vdyktj at vodamail.co.za

Hello Sammym1 - Please give me details about how you constructed your circuit? - you will not need the Arduino midi library with this synth. If possible make4 sure the synth is working before you test it with the Midi keyboard - is the display menu reacting when you press the function button for example?
