PSP Rhythm 2.1 Comes with a drum kit designed after one of our favorite musical artists DAFT PUNK. If you are upgrading from version 2.0 you can just copy your current banks files over the bank files in this version.

v2.0 17th November 2005

Inspired by classic drum machines such as the Linndrum and Roland TR-series, PSP Rhythm has been created to use the simple, yet effective 16 step style drum sequencer. PSP Rhythm incorporates the use of audio sample playback instead of drum synthesis. Version 2.0 has been directly influenced by one of our favorite modern drum machines, the Elektron MachineDrum. The most significant change between ver. 1.5 to 2.0 is our use of "parameter locks" (as used by the MachineDrum). Parameter locks enable you to change the pitch, volume, and pan per step to create moving, changing melodies and effects. This control over your sounds will give you much more creative freedom and allow you to not only use drums, but to use instruments in your music. Song Mode has been enhanced with a mixer function, allowing you even more versatility with your song writing. The user interface has been made more intuitive and easy to use.

Thank you for all of your support.

RCON's Bassline demo September 3rd 2005

RCON's Bassline demo

This is a simple demo of a drum beat and a bassline. The bassline
was created by hacking the wavegen SDK sample (creates a tone that
can be modified with the analog stick) and using a ADSR envelope
that I found here:
to turn the notes on/off.

use the analog stick to bend the pitch and the x button to change
from a saw wave to a square wave form.

So what does this mean? A synthesiser is possible on the PSP!

If you have trouble getting this to work on a 1.5 copy the
"BASSDEMO 1" folder first to your PSP and then the other.

PSP Rhythm Composer is a TR-x0x style drum machine. It features a easy to use
16 step sequencer, 16 drum pattern loops and 16 drum sounds.

-=How to use the drum sequencer=-

There are 16 buttons on the bottom of the screen. Each one represents a step
in a measure. There is a red line above the step currently selected. When you
press the X button the step will light up orange for regular sound, then red
for accented sound and green for flam (hits accented drum twice).

There is a bar above the buttons, the note represents each beat and whole
gray bar shows you which buttons (steps) are in that beat.

To change the drum sounds press up or down on the D-Pad. The currently
selected drum will display on the screen. The buttons on the bottom of the
screen will also light up and show you the programming of the drum hits.

Put drum hits where you like and hit Start to play the pattern.

-=Changing patterns=-

Each button on the bottom of the screen also corresponds to a pattern. If you
move the red selection bar above a button and hit the Triangle key the pattern
will change. There are 16 buttons and 16 patterns available. If the sequencer
is playing then the pattern will switch after the current pattern is done.

-=Using the Menu=-

When the pattern is not playing or in stop mode you can hit select to access
the menu. When in menu mode it will say MENU at the top of the screen.
Below is a list of menu options and how to use them:

Tempo Hit left or right on the d-pad to adjust the tempo
