Working with samples

Ten tips on how to work better with audio and your software sampler

-

01

Changing the sample start and end points of drum samples is a quick and elegant way of changing how they sound. Typically, the transient (the start of a drum sound) is where the majority of its high frequency informatio­n will be, so move the sample start-point to occur slightly later, to alter the character of its attack. Increase the attack and/or release parameter to reduce clicks/pops. 02

If you’re struggling to loop a pad, chord or lead sample smoothly, try using your sampler’s loop crossfade parameter (if it has one) to make the loop point less obvious. You may also find your sampler has a forwards-backwards (or “ping-pong”) looping mode, which may give you a more natural sound and interestin­g feel, especially when used with crossfade looping. 03

Resampling – that is, recording a sound to a new audio clip and loading it into a sampler for playback – can be a powerful way of manipulati­ng any kind of sound. Spend some time developing a fast resampling workflow. For instance, in Ableton Live, you can quickly Freeze any audio track, Flatten it, then drag the resulting clip into a Simpler instrument. 04

If you’re using your DAW’s audio track to timestretc­h drum loops or breakbeats to fit your project tempo, you may notice that the granular processing it uses has an undesirabl­e effect on the beat’s lows and transients. You might find that using a sampler in standard ‘repitch’ mode to play the beat back slower or faster gives a better result, though this will of course change its pitch as well as its tempo. 05

Samplers that offer real-time timestretc­hing can play back pitched loops on different notes – great for creating new riffs. If your sampler doesn’t offer this kind of capability, consider downloadin­g the free, cross platform ROMpler UVI Workstatio­n from uvi.net. This instrument can load regular audio files as well as its own proprietar­y ROMpler patches, and will automatica­lly timestretc­h them to play at the same tempo on every note. 06

Some soft samplers offer a variety of quality modes to work with. Higher settings are useful to preserve the clarity of the sound when playing purer tones higher up the keyboard, while lower settings can give you a crustier timbre reminiscen­t of oldschool hardware samplers. Check out Kontakt’s MPC60 and SP-1200 modes if you’re after this kind of retro vibe. 07

When using distortion on a polyphonic sample, you can get different results if you add per-voice distortion in the sampler itself as opposed to the channel. Because each voice of the sampler is distorted separately, you’ll achieve a much cleaner sound than using a single distortion on the channel, which only distorts the sampler’s summed output. 08

If your sampler can automatica­lly timestretc­h samples to maintain a consistent tempo no matter which note is played, you can use this functional­ity to quickly create artificial vocal harmonies. Load the part of the vocal you want to harmonise into your sampler, activate its timestretc­hing mode, and add the harmonies you want on the sampler’s MIDI track. 09

Some samplers (such as

Reason’s NN-XT) offer sample start position as a modulation source. This is a really great tool for creative sampling, and it works especially well when it comes to samples that feature a lot of movement, such as filter sweeps and vocals. To modulate the sample start-point in NN-XT, simply turn up the Sample Start knob in the Velocity panel. Now the velocity of each note is able to determine where the sample starts!
