How to update Perkons for chromatic play

video upload by Richard DeHove

"Firmware update 1.1 for Erica Synths' Perkons has brought many improvements. The two most notable are the ability to play each voice chromatically and the ability to have the optional hits on the last bar rather than the first. Here I go through the update procedure and the config page options to enable the new features. At the end I get distracted and start faffing about with a dronescape.

The clone, the chicken and a dodgy respray

video upload by Richard DeHove

"The clone is the Joyo 'Monomyth' a direct copy of the Darkglass Alpha Omega Ultra; the chicken is the curious 'Boozer'; and the dodgy respray is me after I change my mind on the pedal's name and mangulate an other wise perfect spray job. So this is just a little bit of fun, and if I seem a bit strong in my criticism of the pedal's original state it's because I would never have bought it without intending to give it a makeover.

If watching an 11-minute pedal makeover is too much then here's the TLDW (too long didn't watch): Getting this pedal's top on and off was a nightmare; I stupidly changed my mind about the name; the end result was OK; and the pedal sounds good with a very strong EQ section.

Create an industrial drone synth on the LXR-02

video upload by Richard DeHove

"Is it an industrial drone synth? Maybe it's an interactive FM sequencer? It's certainly droney with FM sweeps and industrial grind and that's just one variant. Here I create a single synth voice which is then fed with synced LFO modulation. What's most important here is the technique rather than the specific result. My version has a 16-step melodic pattern, but with a few tweaks you could create a retriggering playable voice, or a much slower evolving noisescape using the random LFO waveform. I'm also just using the first voice, but the snare, clap and metal engines have their own flavors and modulatable parameters as well. I was going to look into them as well as quickly creating different melodic "starter" sequences but this was already getting a bit long for something a bit niche. Let me know if you want to go there :D

Finally, from the programming you'll see how easily the LXR performs as a synth. It certainly wasn't my intention to concentrate on the "LXR as a synth" idea, but synthy things start to slip out very easily once you're in the mode.

Patching a basic kit from scratch on the LXR-02

video upload by Richard DeHove

"This isn't a dazzleman superkit showcase video. It's a reality ride-along as I put together a pretty standard kit discussing the various parameters, choices and interactions as we go. It's a moderately long video but then there's a lot to cover and I wanted this to be a real walkthrough of the process. Even so I didn't cover lots of interesting things like LFO sidechaining, panning, effects and velocity - that's for next time.
I put a limiter on the final output to catch a couple of spikes but otherwise there is no other processing than what you see. If listening on headphones you may notice a little noise when the mic is active. There was a lot of ambient noise outside with traffic, birds and power tools - and of course the LXR's buttons are very clicky. With those disclaimers aside I hope you find the process and explanations useful.

Squeezing variations from 16 steps with the DB-01

video upload by Richard DeHove

"Even the best 16-step pattern gets stale after too many spins. Here I look at a few simple ways to create variations without actually writing any new steps or copying patterns. The LXR-02 helps out in the background. The routing is just the DB-01 into the Boss GEB-7 EQ and then into The Glove pedal. The LXR-02 stereo out is being used as two channels - one into the Boss delay, the other into the Mosky Audio muff clone. The snare sounds are panned mostly to the delay and the bass drum mostly into the Mosky.

The DB-01 is the clock master and one voice of the LXR-02 is simply following the melody from the bassline. The 2-bar LFO on the LXR-02 melodic voice gives it a slow wave effect.

As usual there are no other effects, tweaks or modifications to the sound - only what you see.
ps: Still having some camera wobble issues. I'll solve it next time for sure :/

Create multitrack synth patterns in the LXR-02. Demo and tutorial

video upload by Richard DeHove

"Last time we looked at programming synth sounds on the LXR. This time we take a synth-heavy custom kit of four synth sounds and two drum sounds and team it up with the Midicake Arp. The Arp plays the four synth channels. Later we feed all four synths tracks into the LXR in one pass over 64 steps. While the Midicake is ideal for this you could use any sequencer or arp that can satisfy a few basic requirements: It needs to be able to send note information on different MIDI channels and be able to act as the Midi clock master - pretty basic powers. One tiny caution if you're going to use a Keystep-37: When you press the stop button for the arp or sequencer it sends a value '0' on Midi CC51 - which also happens to be the Midi command on the LXR for amp envelope decay on voice 1.

Feeding pattern data into the LXR is a good idea imo given how many options there are on the Midicake. One of the strengths of the Midicake is that it constantly saves its state as you work so there's no need to ever actively save anything. The downside is that there's no saved version to revert to in case you wander off on some promising but ultimately unsuccessful adventure. The lesson is to copy your patch to a new slot as you go. Same holds for the LXR - I've lost many interesting sounds in furious twiddles or too-confident "save kit" actions that turned out to be 'load kit' instead. Stay organized. For my honoured Patreon friends the LXR kit used here is available for download.

The synth sounds on the LXR are really starting to grow on me. They're pretty harsh and digital but respond well to effects. They're also not like your standard synth sounds so you tend to end up in odd places. It makes a good partner for the Midicake. Another obvious partner-candidate would be the Roland 4D. Not a fan of the superb blandness of Roland sounds but spec-wise it seems like a perfect fit. I only have one criticism of the Midicake Arp: They're now made in black and I've got a white one :/

As usual there is absolutely no extra effects, EQ, compression or alteration of the sound other than what you see.

Your LXR-02 drum machine is also an unusual multitimbral synth

video upload by Richard DeHove

"Some machines will never deviate from their designated life mission. Others, like the LXR-02, can entirely reinvent themselves with just a modest push. Erica Synth's little digital drum machine is at heart a six-voice multitimbral synth. The controls are optimised for percussion but it's building blocks are entirely those of synths: Oscillators, envelopes, filters and LFOs. So you're not dressing BoBo the Smoking Chimp with rabbit ears and pretending it's the Easter Bunny. The LXR is already a capable synth.

So here I run through the construction of a couple of synth sounds, meander about through the options, get distracted, lament the poor onboard effects, and end up with a reasonable stereo bassy mid-thing. One small technical note of caution: If you're using a Keystep-37's arpeggiator to play the LXR you may need to go into the LXR's config options and filter the incoming MIDI to just be notes (a single 'N' in the display). This is because the Keystep's 'stop' command sends a CC51 message to the LXR which zeroes Voice 1's decay envelope.

If there's one area where the LXR-02 falls a bit short as a multi-track synth it's in programming and manipulating chromatic sequencer tracks. But a possible solution to that is in the next video...

DB-01 Doom metal pedal test

video upload by Richard DeHove

"In guitarland many people have remarked how closely the Joyo Double Thruster pedal replicates the sound of the Darkglass B33K. Given that the B3K is one of my favorite pedals I bought an ugly Double Thruster to find out how it goes on synth. Originally I thought I'd do a straight comparison with waveform and frequency response blah blah but in the end it really came down to two things:

1) For me the B3K only has one 'sound' and you just dial in more or less of it. Excessive knob twiddling just degrades the effect
2) The Joyo captures about 95% of the B3K sound and has identical controls even down to the bass and mid-boost options and the feel of the footswitch

So forensic analysis seemed a bit pointless. Instead I did what many who lament mono-only pedals do: Run two identical pedals left and right to achieve a type of stereo. That worked pretty well imo and you can see the slight differences between left and right in the waveform display. I also did a quick A and B comparison, but please forgive me the video wobbles - my camera was badly clamped :/

I'm still not sure about the whole clone thing though. The ethics seem to be about defining who's being ripped off: The company or the consumer.

Acidbox III Fully cranked

The many moods of the Future Factory delay (no talk)

video upload by Richard DeHove

"Future Factory by Free the Tone is a stereo delay most often heard creating beautiful ambience. But is is also easily able to do chorus, vibrato, flanging and overdrive (listen around the 9 minute mark for the filth). So here it's teamed with the trusty DB-01, both synced to the same MIDI clock, and the knobs twiddled. The delay comes pre-loaded with 128 presets showing off many of the settings. The interface is certainly unusual but is quite fast to access the various parameters. In the video I mainly tweak the 3-band EQ, modulation and drive. As usual my aim is to give you an idea of what it's like to actually operate and tweak the pedal rather than an idealised selection of sounds. And also as usual I bought this with my own money at full price.

Solina String effects demo: Filters, phasers, drives and dirt

video upload by Richard DeHove

"The Solina's raw sound is not like your standard synth so it tends to react differently to effects. I tried lots of different effects and picked the most interesting to show here. First up was the Erica Synth AcidBox III which, surprisingly, was an excellent match. Using the AcidBox with full resonance was fun and would sound even better with stereo delay but I wanted to keep things to just one effect at a time here. Perhaps the AcidBox works so well because of the lack of controls on the Solina - suddenly the Solina gets an LFO, filter, resonance, input drive and envelope follower.

The phaser test with the EHX SmallStone, Phaser 95 and PH-1r I also found very interesting. For me the Ph-1r had the richest sound and the SmallStone was identical to the onboard phaser.

In the drive, disortion and dirt department the Glove and B3K had their moments while the Geiger Counter ranged from mild to total destruction and some bit crushing at the end.

I also included a short demo with the Boss Slicer, but that thing requires several hours discussion just by itself. Where I'm playing a chord with one note I'm actually triggering a Cthulu chord player in the DAW. Most chords are taken from a custom import of the main string line from Bruckner's 7th.

Astronaut reverb & delay: All 22 effects on synth (no talk)

video upload by Richard DeHove

"Astronaut by Shiftline isn't a standard reverb or delay pedal. It can certainly do 'standard' reverb and delay but with one or two knob turns you'll find yourself deep into ambience, noise and droneland. There's 22 effect algorithms and here I noodle extensively with each one. As usual I thought it best to show the pedal by itself with no other effects and with minimal cuts to give a clear idea of what it's like to twiddle the knobs.

I bought the Astronaut used on a bit of a whim: It looked good, had a good name and promised weirdness - all excellent reasons. In many ways it reminds me of a Strymon, except way more extreme. Originally I was going to do extensive blabbing about this pedal since there's a lot to talk about, but after almost an hour just of noodling I thought the blab should wait for another day.

Just a couple of things of note: The center knob selects the algorithm, while the four outer knobs all have primary and secondary functions. From left to right the secondary functions are: Volume, HPF, LPF and stereo field. You access the secondary functions by holding down the right-side switch. During the noodling you'll mainly see me adjusting the filters. Otherwise the primary four knob controls are: Character (which changes depending on the algorithm), delay/decay, mix (from dry to 100% wet) and time/speed. If that's a bit murkey then the manual is excellent:

The full manual: https://shiftline-shared.s3.amazonaws...

One aspect that's particularly interesting. There's no save function here. Instead whatever state you happen to leave the algorithm in when you switch to the next one is what you'll get when you come back. This is both incredibly convenient and dangerous: One knob twiddle and your favorite sound is now modified. OTOH there are also 11 user slots where you can easily copy any sound so you could use that as your "don't touch" zone. Those two factors make this one of the best pedals I've used in terms of saving sounds. Often preset management on pedals is painful.

Finally there are all sorts of ways Astronaut can be configured. If you want you can even change the parameter range of the knobs! There's options for MIDI CC control, analog triggers, MIDI clock, line and instrument input. You can even change the beat switch time divisions to your own exotic time signatures. So there's a lot to like.

DB-01 sound design from bleedin' obvious to drum phase offset

video upload by Richard DeHove

"Sound design on a one oscillator bass synth? Yes, a surprising amount. A lot is tied up with the sequencer but there are also some pure synth tips in there as well. Some of them, like filter tracking, I've talked about before so perhaps this is like a "best of" compilation. But it still seems to make sense to have them all in one place. For impatient veterans perhaps only the last section on LFO phase will show anything of more hardcore interest.

Perkons driven by the Midicake arpeggiator (no talk)

video upload by Richard DeHove

"Two examples of the Midicake Arp driving the Perkons drum machine. There's no patterns or steps programmed here, just MIDI triggers sent from the Arp. Each voice is on a different MIDI channel. Variations are created by a gentle modulation of the beats/bar parameter and the two modulations channels variously affecting velocity, groove length and the rhythm pattern length. Timings on individual parts have also been tweaked using the delay parameter. When you see the orange light on a channel it means that part is muted.
The Arp is of course blind to what might make a pleasing drum pattern so it's a little bit chaotic at times but overall I think it's an interesting end result. If the drums weren't the main focus of your performance, but you needed something that continually changed to the avoid simple continuous loops then this might be a good solution. By switching kits you can also create some interesting fills. And while it might all be a bit loose as a jam, it could easily be chopped up into something much more coherant. And a drum machine that was able to receive note information (like the LXR-02) would be even more interesting.
The Geiger Counter provides some grit and there's also a little Fabfilter Pro-R on the kick (which was taken as a separate out).
Anyway, just a little noodle for your consideration and amusement.

Getting started with the Midicake Arp

"It's described as a 4-part arpeggiator and is even just called 'Arp'. But I think it's better characterized as a 4-part algorithmic phrase sequencer. Because this isn't just a dedicated box with standard arps. It can create long chains of constantly changing sequences which are directly created from your live keyboard input - and it all stays in perfect sync. This half-hour video should at least give you a reasonable taste of what it can do, or if you're a new owner, be enough to get you started.

Perkons through four flavors of filth

video upload by Richard DeHove

"Two Perkons patterns playing three kits tested through four pedals: the WMD Geiger Counter, Fairfield Circuitry Roger That, Darkglass B3K and JPTRFX Add Violence*. I contemplated cutting this down to a four minute highlight video but I think there's real value in showing the actual process of tweaking to get the best sounds. But maybe I'm wrong. What do you think? Show the best bits only, or show the process?

In any case you can see in both the Geiger Counter and Roger That where tiny adjustments can have profound effect on the output and it's pretty clear they get the biggest range of different and usable sounds. The two "small" pedals really only have a single core effect and can only get relatively modest variations from that. But horses for courses. To balance the varying volume levels I had to be quite heavy-handed on the limiting, so some of the louder sections have been squashed (Fabfilter Pro-L and Cockos ReaLimit). Generally the Geiger Counter had the most consistent volume and was most easily adjusted on the pedal itself, whereas Roger That and Add Violence tended to be most difficult to tame. * NB: I've adjusted the internal trimpots on Add Violence and they have a huge effect on the sound. I've no idea how far I've diverged - for better or worse - from the original values! (I must do a video where I adjust these in real time. It's such a shame they aren't actual knobs).

Down in the Park [Numan cover] on Solina and Perkons

"Gary Numan's 1979 single 'Down in the Park' has always been a favorite of mine. This cover version (instrumental) has been made using only the Behringer Solina Strings and the Erica Synths Perkons drum machine. The Solina plays all the synth parts while the Perkons does drums and the sub-bass deep hits best revealed on headphones. The images are AI generated using Stable Diffusion.
It wasn't my aim to make a 1:1 copy but in the end I stayed pretty close to the original. Any time I started changing things it felt like I was insulting an old friend.

Acidbox III extended demo with Perkons

video upload by Richard DeHove

"A stereo filter at the end of an instrument with four multimode filters? Why not, makes sense to me. I've been hunting an interesting filter for ages - preferably stereo. I've churned through the extreme Retro Mechanical Devices long-name-bigbox to the more recent Elta Polivoks, Source Audio Ultrawave and even the filter on the Strymon Mobius. All the of them are gone now except the Mobius.
With the Acidbox III I think I'm close to the answer. Of course the filter itself is the essential core, but two other aspects make this shine: a syncable multi-waveform LFO, and the classic Erica feature of overdrive on the input. Here I noodle around on a single Perkons pattern with a rare touch of the DB-01 just for a sonic change. Routings are explained in the video. There's no other processing than what you see.
