From the Manual, Page 75: “All sample speeds from 4 kHz to 48 kHz are accepted and handled by the Machine- drum UserWave. Higher rates are accepted but the samples are downsampled to half the sampling speed. The Machinedrum UserWave does not handle stereo samples. All bit depths are accepted but will be played back at 12 bit.”

TIP: By lowering the bit rate you also lessen the size of the sample. By lowering the sample rate you it will diminish the quality of the sample, which in some cases is a desired effect.

A Note from Elektron: “12 bit samples loaded into the Machinedrum will take actually take the same amount of storage space as 16 bit samples will. If you want to save space I recommend to convert the samples to 22 kHz.”

• There a many different ways to efficiently use your sample space. 2mb or 2.5mb can go a long way if you’re crafty with your samples. Lower sample rates is one method.

• Pitching samples up will shorten the length of your sample. Once loaded into the ROM slot you can repitch the sample.

• Anything below 44.1khz will also reduce the sample size.

• Using mono samples instead of stereo also reduces the sample size.
