Album Release.

Today seemed like an appropriate day to start finishing my album.
It's a collection of 6 of my best recent tracks, and can be found online here.

It features a reasonable amount of variance, some nanoloop, underclocked sounds, sampled drums in LSDJ, re-sampled sounds sequenced using a monome.

I'm pretty happy with it. I've printed up some covers and will be handing them out at my upcoming performance at the campus band comp.

More on underclocking.

I decided to underclock one of my DMGs today.

I didn't have the exact 2.097152MHz crystal required for a halving of pitch in tune with the original crystal, but a 2MHz crystal should be fine, and sounds great intune with itself.

Heres a few pictures of the result. And a song I wrote using the underclocked DMG and a copy of Nanoloop.

(you'll have to click on these images to see them at full size)

Here is where the original crystal was, and you can see the wires leading to the new crystals.



You can see where the switch was installed, and where I placed the two crystals.



Because i removed the dc socket for switch placement, I had to bridge this part of the board so power would still run through.(if you dont do this, the gameboy just doesn't turn on)







Here's a comparison of start up sounds just to show the difference, first full speed, second is half speed

Underclocking/Overclocking.

While the Gameboy has a decent range, when exploring influences such as dubstep and drum and bass, composers often want to go lower, to get deeper, fuller bass.

While artificial pitch shifting can be achieved easily with computers, it usually results in artifacts and leaves the sound not as good as it could be.
This is where underclocking becomes a good option.

The following video presents one clock changing option, giving the user realtime control over clock speed.


However, the more popular(and easier) option, is to change the crystal oscillator, from 4.194304MHz to 2.097152MHz, although due to the difficulty in finding 2.097152MHz crystals, 2MHz is usually accepted,(the machine stays intune with itself, but is slightly off others)

A guide to this method is available here http://gieskes.nl/underclocking_or_overclocking_the_gameboy_classic_tutorial/

This guide also presents the idea of overclocking, allowing the Gameboy to play at faster speeds and higher pitches.


And here is a song made by Sydney chiptuner Ten Thousand Free Men and Their Families that was written on an underclocked DMG using LSDJ
