I tend to use these controls to add just a small amount of extra harmonic content to help my kick drums cut through on small speakers. The Asym slider will add more harmonics at multiples of the fundamental whereas the Saturation slider and Slope knob add only odd harmonics. Once you’re happy with the shape of your kick drum, Ultrabeat has lots of options to alter the timbre of it. (Listen to Audio Example 1 - the first two bars are Ultrabeat and for comparison the last two bars are Maschine’s Sub kick drum generator). It is also worth spending time experimenting with the decay curve of the amplifier envelope, as this will significantly change the decay characteristics of the drum sound. A curve that decays quickly will tend to give a click that has more high frequency content, whereas a slower decay tends to add more mid-range weight to the initial thump. To change the character of the click tweak the curve of the envelope using the decay curve handles (see Screen 1, above). You may need to use the zoom function to achieve this. Then go to envelope 1 and adjust its Decay to 7.6ms. First increase the pitch modulation amount to F5 (this is the blue transparent control in the same curved section of osc 1 as the pitch control). Conveniently, envelope1 is already routed to osc 1’s pitch. To give the kick that characteristic click at the start, we will use an envelope to modulate the pitch. This is our amplifier envelope set the attack to its minimum time to ensure the envelope is as snappy as possible then adjust the decay to 720ms this should make our 808 long enough to have a satisfying amount of bottom end but short enough so that each kick doesn’t just blur into the next. Now go to the envelope section and click on envelope 4. This effectively sets the lowest useful pitch our 808 can achieve when playing C3 on the keyboard. Start by going to the osc 1 pitch slider and set it to C0.

Regardless of how an original 808 kick drum sound generator worked, a reasonable approximation of an 808 kick drum can quickly be achieved using a single oscillator, an amp envelope and a pitch envelope. We are going to focus our efforts on Ultrabeat’s highest slot - slot 25 - as this can be played chromatically from C3 upward on your MIDI keyboard. In a new project call up Ultrabeat and from its Preset drop down choose Tutorial Settings / Tutorial Kit preset. Let’s start by creating a basic 808 kick-drum sound, chromatically laid out across the keyboard so you can play the kick drum as a bass line. To round off our journey into drum manipulation we’ll use Alchemy as a processor for real-time manipulation of existing ESX24 libraries, turning them into something more varied and interesting.

We will then look at how to combine our synthesized kick drum with a multi-sampled kick drum. Dedicated drum synths like those in Native Instruments’ Maschine or FXpansion’s Tremor are often mentioned for the quality of their results, but equally good results can be coaxed out of Logic’s stock instrument Ultrabeat, with a little effort and know how. In this month’s Logic Notes we’ll begin by looking at using basic drum synthesis to craft your own kick drum sounds so you can take control of their length, shape and timbre. If you find yourself spending ages auditioning drum samples in a quest for the right sound then learning more about drum synthesis could give you a viable alternative.

Changing the curve of the decay portion of the envelope will significantly change the timbre of the click.ĭesign and manipulate your own kick drums from scratch using Ultrabeat and Alchemy in Logic Pro X. Screen 1: In Ultrabeat we can use envelope 1 to modulate the pitch of oscillator 1, adding a reassuring click to our 808 kick-drum sound.
