KIT AVAILABLE !!! All In One v2.7 PCB Kit to sell !!!

[Synthex]

how about a step by step guide for beginners to have set all the components?

What do you want as explanations ?

is easy to set all the sensitive parameters?like a roland td-3 one?

It's very easy !

I´m interested in the megadrum,but before all,i want to know if it´s easy to finish after buying synthex kit.

Any opinions of people who have already bought and mounted the kit ?

With this version, there is not any more of bat85 !
74HC4851 (or MAX4558) replace bat85 diodes, 100 ohms resistors and 4051 ICs.

ICSP Atmega32 Connector :
1 - MISO (PB6)
2 - MOSI (PB5)
3 - SCK (PB7)
4 - RESET
5 - GND

from "Components List and Pinouts v2.7.txt"

With this "In-Circuit Serial Programming" (ICSP), you can program the Atmega memory.
If the Atmega is already programmed with the Sysex Bootloader (like in this kit), you can upgrade the firmware by MIDI over USB.

hi synthex, got my kit earlier, thanks for that, about the icsp controller, do i only need that if im going to change the firmware? the IC's are already programmed and ready to go though yes?


also does anyone know anywhere that can supply 20MHz crystals, my local place doesnt. What do MISO and MOSI mean?

thanks again

IC's are already programmed and ready to go.
You can use Sysex Bootloader to upgrade firmware with a future version.
