SWooh-arrMR1

This is what you might get when the producer feeds the orchestra too much red caffeine drink...

The story

Sometimes inspiration strikes at the most unexpected times. In this case, I was doing a review of another Pianobook.co.uk virtual instrument (Sample Pack in PBCU-speak) and I thought: ‘Ooh, that’s interesting!’ as my head went in a totally different direction. Some hours later, SWooh-arrMR1 is the result, and yes, it’s a pun.

Although it might look like this is jumping on the Global Swarm meme, it’s actually something that I’ve been thinking about in the background for quite a while, and there are bits and pieces of SWooh-arrMR1 in some of my earlier releases – I’ve previously revealed that I gradually work towards end results in small steps, rather than giant leaps…

SWooh-arrMR1 is a ‘Swarm Generator’. It mixes bits of ‘Drone Drone’ and ’Straight Maths’ (think of a Roland Synth…) to give something rather different as the result. Like ‘Drone Drone’, the idea is to play notes slowly and deliberately for an effect to emerge, rather than the ‘play as many keys as possible as fast as possible’ technique which is sometimes seen as impressive.

The source material

Taking the cue from ‘Straight Maths’, a previous virtual instrument, Claude Risset, Karplus and Strong are pressed into action once again. The raw audio material was humanised and realism-ised in various ways that involve detuning, envelope variations and all sorts of processing that are not a million miles away from what people think makes analogue synths special. File under: ‘He messes about with the audio so it doesn’t sound sterile…’. One of these days, I may write a blog post about what I do, you never now…

From those raw sounds, I employed temporal and spectral stochasticism to make them repeat a few times at random time and timbre intervals. This time, I took great care to make samples that would be in tune, and where an A really is an A. Not that this has ever resulted in a rejection from PBCU Central before…

The sound sliders: A, B, C, and D

There are 4 ‘mic’ sliders, which are effectively a sub-mixer that lets you set your favourite mix of four samples and their positions in the stereo field. Unlike some previous virtual instruments, SWooh-arrMR1 uses mono samples, and lets you set their pan positions, so there’s no wildly different sounds in the left and right channel, as might have happened earlier in an other virtual instrument or two… The samples are all of different lengths (deliberately, of course!), and they are all looped. I also cheated big-time with the round-robins by just detuning individual samples (Previously, one reviewer noted, with what some might interpret as alarm, that my instruments had different beat times between the same intervals, every time you played two notes – which I took as praise!) The sliders are faintly coloured in rainbow colours (well, four of the set, anyway, and where is BROWN in the colour spectrum?) because it makes it obvious that they are different things, almost like the A, B , C and D letters above them. There are two types of sound: Percussive (Perc) and Plucked (Pluck) which differ in the way that they are generated and in the way that the spectral content changes over time.

It’s a mixer! Move sliders A, B, C or D, or any combination, upwards and you will get a mix of up to four timbres. The exact sounds that you get depends on the settings of the ‘Articulation’ menu, but that’s for later. For now, just hold down a note and adjust the sliders until you get a sound that you like. This is also a good time to set the pan controls, which slide to the left and right for each of the A, B , C and D sounds and so set where the sounds are in the stereo image. In the centre will be boring. To the side will be more interesting, but will not have as focussed a position in your stereo field, and so will upset mixing gurus.

Before you spend too long on setting up the sliders and the pan controls, don’t forget that Decent Sampler’s stereo chorus effect and reverb do blur the timbres and their associated stereo image, so you need to centre the pan controls and use outboard effects if you want more control over stereo imaging. It’s a bit like mastering – will anyone ever hear those reversed vocals? Actually, they might! But don’t do the ‘three years to get the second single perfect’ thing, because that’s not compatible with today’s Ify Spot ‘release as fast as you can, as often as you can, so you make me richer’ ethos where you never seem to make any money at all…

The four sounds are just single samples stretched across the keyboard. They aren’t multi-sampled, either across the keyboard, or for round-robins, or at different velocities. In this application, that would be ‘gilding the turnip’ as someone I know says. Once again, it is ‘Ify Spot’ thinking – if you are never going to hear the effect of samples recorded at different velocities, then don’t sample them like that!

– – – – –

Here are some notes on how it works, and how you can use it.

The User Interface UI may look scary and complex at first, but don’t panic! (Well, actually, you CAN panic because I’m not going to force you to do anything, but when you have calmed down, then come back here and continue reading.)
Lets break it down into sections:

Left-hand panel

On the left of my logo, there are 4 vertical ‘mic’ sliders for the 4 sound sources – see the ‘Sound sliders’ section above for more details. I called them A, B, C and D, which is simple and slightly mysterious, and then I went and ruined the surprise by dividing them into two sections called Perc and Pluck.

Using multiple ‘mic’ sliders can stress Decent Sampler’s polyphony under some circumstances, so don’t set all the 4 ‘mic’ sliders to maximum in the assumption that this is the best or optimal sound. Instead, try using only one or two sliders at once (less is more), and remember that you have control over low frequencies with the High-Pass Filter (HPF) as well as high frequencies with the Low-Pass Filter. Of course, just to confuse you, using all four sliders with different pan positions sounds really cool! So do, or don’t, use four sliders, is that clear enough?

Oh, yes, and there’s also that ‘Articulation’ menu that was mentioned earlier. It is just underneath my logo for PBCU. This has three options: All (the default), Sparse and Thin.

All – this throws multiple octaves AND inverse round-robin detuning into the ring – use this for slow builds and drones.

Sparse – this has multiple octaves and spreads them out with the round-robins.

Thin – this has neither the inverse round-robins, nor the multiple octaves, and so sounds thin – which is good for busier playing.

Right-hand panel

To the right of my logo, there is the ‘processing’ section, which I have simplified, honest!

From the left to the right:

First, the Expression control, which is mapped to MIDI CC 11, gives you a vertical slider that controls the output volume of Decent Sampler. This is how you control the volume or loudness, of the sound!

The big round control in the centre, the ‘Release’ rotary control, sets the Release time – how long it takes for the sound to fade away after you stop holding keys down. In this application, the Release time can be very long – up to two minutes if you want. To the right, is a tiny slider that says ‘(Attack)’ at the end of some explanatory text – basically this sets the rate at which notes get louder when you first hold a key down. So the sound gets louder at the rate set by the attack time, then it stays at the maximum (sustain) level, and it stays at the sustain level until the key is released, and then it fades away at the release time rate. Fade in, hold, and fade out. You’ve probably seen Christian Henson do exactly that with his Doepfer master keyboard…

The next area has one small slider and two big sliders. The small HPF slider is a High-Pass filter, and this removes low frequencies from the sound, making it thin in timbre, and for lower pitched notes, even removing the fundamental. Most of the time, this can be set to the 0 (lowest) position – but experiment! The LPF (Low Pass filter) slider controls the cut-off frequency of a 2-pole low-pass filter high is open, letting all frequencies through, low is closed, letting only low frequencies through – the Tone control is mapped to MIDI CC 1: the Mod Wheel the grey bar next to the virtual keyboard. There isn’t a Q’ slider in this ‘simplified’ implementation. Don’t be afraid to try moving the HPF and Low-Pass Filter sliders around – there is a lot of control over the timbre available! The sounds from the source sliders are deliberately bright, so that you can cull harmonics using the HPF and the LPF controls. Have no mercy – filter those frequencies like it’s 1999…

The final area has only two sliders. They control the Reverb effect. The ‘Space’ slider wobbles the pitch of sounds in the room that the reverb is emulating, whilst the ‘Wet’ slider controls controls the amount of reverberated sound that you will hear. The dry sound is always audible. The ‘Wet’ slider is mapped to MIDI CC 19. I over-use reverb, so your job is to reduce it! (Ever wondered why so many factory sounds have too much reverb on them?)

Presets

My user interfaces (UI) are scary for some people, so I have included a few presets. The names might give some hazy pointers to the type of sound, but this can be very subjective… One of my recent faves was ‘Angry Insects’…

UI

There is no need to be intimidated by all the sliders – just concentrate on one of the areas at once and you should be fine. There is always that big round ‘Release’ control – no connection to the Spitfire UI at all – that will help you to release the sounds from this virtual instrument!

As you can see, I’m exploring making my interfaces simpler, just as more complex interfaces seem to be more popular. Life is like that: some people are just out of step with the universe.

The sounds…

SWooh-arrMR1 is an atmospheric swarm generator. Use it to build tension before a break or a cue. Use it as an unsettling, busy pad without the cliches of violinists who have been drinking too much Red Bull, or of fast synth arpeggios. Use it in YOUR way, and invent a new cliche!

MIDI Controllers

1 ‘Modulation Wheel’ controls the Low-pass Filter Cut-off Frequency, the ‘Tone’

11 ‘Expression’ controls the output volume

19 ‘General Purpose 4’ controls the Reverb Wet/Dry mix

The video below shows how some bits of the user interface works, although it uses a very different instrument as an example. One day I may make a different video that is better suited to my latest controls…

  • Another stunning instrument!!!

    Thanks master. This is another interesting instrument.

    Not sequenced, but repeated plucked sounds. Percussive or plucked, it doesn't matter, but it sounds lovely.

  • Samples never disappoint

    Literally every time SynthesizerWriter uploads a new library I will not hesitate to download. Never disappointed with the patches and this one is no exception. I love everything about the sounds, the attention to detail, the creativity behind every interface. This one gives me goosebumps, and definitely will find myself using it for cinematic purposes. What an inspiration!

  • Unique and usable

    There are some very unique sounds in this library and all are usable. These could be used to "underscore" or be the focal point of a composition. They would also be very usable in a cinematic score for many genres where a tense or unsettling sound is called for. Thanks for the contribution.
