All seems ready to go but no go

Post by bryan_gibbs »

I completed the build and tested/troubleshot the whole way. Analog section works but I can not get the sequencer to work. Tempo light is flashing and the rate changes when tempo knob is turned, pattern bank lights up and I can select 1 to 16 but I can not get the sequencer to run in random play mode or any mode for that matter… All Leds light up when Numbered Keys are pressed, R/S button lights up but no sound. Any thoughts?

my first suspect is that there are no actual patterns in there
switch to Keyboard mode, and press the keys to see if that makes it produce sound

It's also possible that the highest bit from the Mode switch isn't there. In this case the various play and write modes would actually work (but of course not without programming a pattern first) but the higher modes (like keyboard, random, MIDI play) would not.

no mode even random play does not create any sounds neither does keyboard mode. Is it possible that the mode switch is damaged?

if you've installed the USB-Serial driver, you can hack-in a pattern via BANNED and see if the sequencer works then:
- run BANNED, use "Connect to x0xb0x"
- once you get connected - go to the Pattern Editor menu
- set Bank 1, Slot 1 (actually, that's the default..)
- hit the Load button, and select this file: Armando - Land Of Confusion.nsp
- press CTRL+S, to save the pattern to the x0xb0x
now, on the x0xb0x, set the BANK selector to 1 and press pattern slot 1
you should be able to play this pattern, hopefully

if it doesn't connect for some reason - report back what kind of error occured

I see two possible scenarios:

1. A problem with the Mode switch
2. The digital signals don't "make it" to the analog side.

It looks to me as if the digital side is working in general; the switch scanning basically works (otherwise you wouldn't be able to use the Bank switch). So let's see if the different modes are actually accessed or if it is stuck in one or several modes.

Please check in which modes the Tempo LED is blinking. This should give us something to work with.

I turned the mode switch and each selection of a mode has the tempo light blinking.

I also tried using BANNED to connect to the x0xb0x and all though my mac recognizes the usb to serial adapter, shows in about this mac, BANNED freezes on startup. I'm running os x 10.8.5 so I'm not sure if thats the issue.

a screenshot might help

The screen shot is what happens if I let it try and connect. Just sits looking for firmware version.

oh, when you said "the app freezes on startup" i thought it doesn't even reach the menus at all..

"/dev/tty.Bluetooth-PDA-Sync" <- this looks wrong to me
on osx, the x0xb0x should appear something like "/dev/tty.usbserial-xxxxx"

make sure you've properly installed the FTDI driver, and that the x0xb0x is appearing as a "usb-serial" device when plugged to the computer..

i can't see anything useful there
try this: open a terminal window and type: ls /dev/tty.*
