![]() (In an analogue delay, you could think of the electronics or the tape loop performing the same function as the memory in a digital delay.) Multiple echoes or 'repeats' of the programme material are produced by feeding a percentage of the delayed material back from the output of the delay buffer into the input. We refer to this time difference as the delay time. As the name suggests, the way in which delay processors work is quite simple: the programme material passes through a memory buffer and it is then recalled from the buffer a short time later. Note that I've used exaggerated effects levels in the examples, to highlight the sound of the delay.įirst, let's run through a quick overview to get any newbies up to speed. I'll be writing primarily about the sound of different delay configurations, and to make things easier to follow, I've created an illustrative series of audio examples (see ' Audio Examples' box for details). The aim of this article is to focus on the practical applications of delays, by looking at some ways they're typically used on vocals, guitars and synths. Why? Well, delay isn't only an effect in itself it's also one of the basic building blocks for many other effects, including reverb, chorus and flanging - and that makes it massively versatile. If I had to pick a single desert island effect, it would be delay. The familiarity of geometric waveforms, the flexibility of custom-drawn wave-shapes, and the innovation brought through the inclusion of a center and scaling parameter creates a unique and powerful tool, which can comfortably be a part of your own Ableton Live sessions.Delay forms the basis for a wide range of effects that can transform your tracks from dull and pedestrian to polished and professional. Observer is a highly useful tool that can bring life into sound design, composition, and mixing, by allowing users to seamlessly control multiple parameters with the help of a simple and elegant tool. This feature has been added to the LFO and custom waveshape modes. By clicking on the “nt” button, you get triplet notes, and by clicking on the “nd” button you get dotted notes. With note values, you can select whole notes, half notes, quarter notes, eight notes, sixteenth notes…all the way down to 64th notes. LFOs can be synced to the tempo if desired-you can switch between setting a frequency in hertz (frequency mode) or a frequency in note values: Observer also has two ways in which it can interact with user MIDI input:Ī) In auto mode, it ignores MIDI input and it modulates parameters at all timesī) In MIDI mode, the modulation output is retriggered each time a MIDI note is entered, and the modulation is engaged for the duration of the MIDI note. d) You can control the folding – which allows you to determine the mod source’s behavior when it reaches the edge of a parameter’s value.c) You can control the polarity – which determines the directions in which the modulation moves the parameter.b) You can set a center – which determines the point from which modulation is applied to the parameter.a) You can scale the amplitude of the modulation – which determines the depth of the effect. ![]() ![]() A delay control for each source allows the user to put the mod sources out of sync, leading to a unique interaction between parameters.Ī distinctive feature of Observer is that it allows you to manipulate your mod source in a variety of useful ways: Also, each one of the four modulation sources can have up to four destinations – allowing for a single mod source to control four parameters simultaneously. Each of these sources can use one of the 3 available modulation methods, be it a geometric wave, an ADSR, or a custom waveshape. Observer’s minimalist design presents the user with four modulation sources. Featuring traditional geometric waveforms, an ADSR, and a custom mod-waveshape designer, you can assign up to 16 parameters to be controlled by a single instance of Observer. Observer is a patch that lets you harness the powers of Ableton Live and of your own plugins with a flexible and intuitive modulation engine.
