On this CD you will find 30 patterns each recorded in 10 different tempos, reason being you might not just want to produce fast techno tracks but also have the possibility to create some slower tunes as well. Time stretching is an awesome technique and the algorithms nowadays have reached overwhelming quality but it cannot perform miracles and trying to stretch a recording in 130 bpm down to 80 bpm would not sound very realistic (although with this CD you do have that option as well). All patterns are recorded in 70, 80, 90, 100, 110, 120, 130, 140, 150 and 160 bpm.
The TB-303 is most famous for its unique sound while turning the filter knobs (Can be heard on, what’s considered to be the first acid tune, “Acid Tracks” by Phuture) and even though this is a nice CD it is still just a collection of audio recordings and you do not have the option of tweaking yourself. To make this collection as flexible as possible I have tried to record in such ways that you can use different parts of a recording for different parts of a song. E.g. if a pattern is based on a 16-bar recording, the first 4 might be a plain bass, the following 4 with the cutoff filter opening and the last 8 are tweaking the filters. This will provide the tools for a classic acid build-up and climax. All patterns are recorded differently and some use that structure in the example above while others are only the tweaking part and some are only recorded without touching the knobs for a few bars – it depends on the style of the pattern and some patterns are simply not suitable for any ”tweaking orgy”.
Another famous sound of the TB-303 is the distorted sound that can be heard in the harder and modern developments of acid, e.g. DJ Misjah’s ”Keep Your Love” or ”Everybody needs a 303” by Fatboy Slim. I have not included any distorted audio samples on this CD as you can easily apply it on any pattern you want with your own favorite distortion effects.
All audio files are recorded in wave format, 44.1 kHz, 24 bits mono and are normalized to -0.2 db. They are then converted to 16 bit 44.1 kHz. The recordings are all in mono because the TB-303 only has a mono output and converting these recordings into stereo would have taken twice as much space on this CD. None of the recordings have been processed with effects, compressors or mastered in anyway – only normalized. There has not been any post processing using noise reduction or EQ, although I have tried to keep the noise level to a minimum during recording. The goal has been to give you as raw recordings as possible to use the way YOU want.
On all audio files I have also included a header to let the audio production tool know what tempo that has been used and for how many bars. Please understand that your audio production tool of choice must be able to automatically discover this. If not, don’t worry. Each file has been named with the proper tempo it was recording in, e.g. ‘Pattern_03_110.wav’ was recorded in 110 bpm.
