FM Synth Tutorial – Low Pass Filters with the RedLion FM Synth

Every good synth has a fantastic low pass filter that can be used in a variety of ways to create an array of interesting sounds and to add ‘movement’ to your patches.

The RedLion FM synth is no exception. It features a fully resonant low pass filter with additional ADSR envelope control.

This video is a complete guide to using the low pass filter within the RedLion FM synth..

FM Synth Tutorial – Intensity and ADSR Envelopes Tutorial with the RedLion FM Synth

Intensity plays a key role in creating the kinds of sounds we want from our FM synthesisers. Whether this is carrier intensity or modulator intensity, it can help sculpt the sound and type of sound that we are looking to create.

The RedLion FM Synth enables us to manage the intensity of our signals in a variety of interesting ways, including the use of a per-signal ADSR envelope. If you aren’t familiar with envelopes and ADSR then check out our post explaining ADSR envelopes in detail.

This video takes you through all of the ways of manipulating intensity in RedLion that you can use when creating your own amazing sounds..

FM Synth Tutorial – Ratios and Tuning Concepts with the RedLion FM Synth

The concepts of ratios and tuning are of fundamental importance in FM synthesis.

Ratios determine the relationship between the incoming note(s) frequency and the frequency of a signal, be it carrier or modulator. Using this technique we can change the pitch of carrier signals on either a constrained (octave) or unconstrained (free select) basis.

The ratio of a modulating signal to the incoming note frequency determines the effect created by the frequency modulating – the best way to understand this is to download a copy of RedLion and try for yourself!

The fine tuning knob in RedLion can be used in conjunction with the ratio knob to tune to particular intervals or can be used to move two (or more) signals slightly out of tune and produce a range of beating and phasing effects.

This video demonstrates all of these concepts using the RedLion FM synth VST/AU plug-in. Enjoy!

Song of the Week – David Alexrod : Holy Thursday

By Simon Hampshire

Well, the sun is shining and I’m sitting at my desk listening to David Alexrod’s ‘Songs of Innocence’.

Somehow I have gone through several decades of my life without encountering Mr Alexrod’s work until I chanced upon this album last week.

On first listen of ‘Holy Thursday’ I very quickly realised that the music was elevated above the norm – amazing late 1960s production and a bevy of outstanding musicians combined to create a stonking romp through a variety of styles in a manner which is at once entirely homogeneous and also difficult to place.

The nearest comparisons that leaps to mind are soundtracks of the era. Indeed, it put me in a mood to play ‘Sexopolis‘ by Jean Pierre Mirouze at the first opportunity, which is always a very good thing.

When listening to ‘Holy Thursday’, I was immediately struck by two things. Firstly the beautiful production was enchanting – starting almost as an earlier jazz-sounding recording only to change it’s mood entirely when the drums entered the fray. Secondly was those drums – prominent in the mix, played exquisitely and recorded so that they sound both natural and expansive. I was captivated at once.

Add to this some lovely, percussive bass, lush strings and an aggressive burst of electric guitar towards the end and Alexrod has created a masterpiece. It all seems to fit together so seamlessly and is so entirely memorable in a way that is hard to define.

I can heartily recommend the entirety of the the ‘Songs of Innocence’ album – just make sure you don’t unintentionally confuse it with the sorry U2 offering! If you need to pick one song as an entry point, however, choose ‘Holy Thursday’ and never look back.

FM Synth Tutorial – Signals, Carriers, Modulators and Waves with the RedLion FM Synth

In Frequency Modulating (FM) synthesis, carriers are the origin of our sounds.

RedLion is an 8 signal FM synth and each of the signals can be used as either a carrier (an audible wave that is subject to frequency modulation) or a modulator (a modulating wave that is not audible).

The sounds hear from an FM synth are made up of the outputs of all active carriers, modulated by any active modulators.

Whether a signal acts as a carrier or modulator is determined by the algorithm selected. When a signal number has yellow text and is present at the bottom of the algorithm, the signal is a carrier. Signals featuring white text will operate as modulators.

This video explains these concepts in detail and demonstrates these concepts with RedLion.
