"In this video, Dylan shows you five different ways to elevate the sound of your drum beats and get your drums feeling less robotic and more human with our Launchpad Pro.
MIDI drums offer music makers lots of flexibility to change the sounds of drum elements on the fly and make minor adjustments at any point, even after your track is recorded. But this can leave them sounding a bit robotic, with every hit at the same velocity, strictly on the grid, and generally not capturing the nuances of a real drummer. But here's how to fix that!
Watch the video to find out five distinct ways to make your beat sequences sound and feel real whilst adding life to your drum grooves.

"Selmer Companion reed organ from the 60s. In tune and wonderfully “parlour-harmonium”: bright, reedy mids with a gentle breathiness on the attack, then a steady, organ-like sustain from the blower. The chord buttons give an instant drone bed with that slightly nasal, woody timbre that cuts through without ever getting harsh. Think small chapel/folk harmonium vibes—perfect for drones, hymnal pads, psych-folk textures, lo-fi soundtrack cues, and vintage pop hooks. Hear it in the demo (skip to last photo). Typical vintage tuning and keybed feel; expect minor variance vs modern concert pitch.
Features
Classic electric reed organ with compact keyboard and built-in blower/speaker
Left-hand chord section: Major & Minor buttons (C, G, D, A, F, B♭) for instant accompaniment
On/off/level control, integrated flip-up music rest in the lid, suitcase-style cabinet with carry handle
1960s/70s Italian vibe: gold fascia, cream case, and period hardware
Sounds exactly like you want a small electric harmonium to sound—see the demo"

Discover the Sacred Sounds of the Past: A Generative Sequencer Inspired by Medieval Chant
Immerse yourself in a groundbreaking tool designed for creators of ambient, experimental, contemporary music, IDM, and electronica. This Max for Live generative sequencer fuses historical depth with cutting-edge technology, offering a unique journey through time and sound.
Historical Roots, Modern Expression
Developed over a year of intensive research, this device draws from a rich tapestry of medieval chant manuscripts and the intricate patterns of neume notation. Delve into the essence of the eight church modes, enriched with the proto-characteristics of Ionian and Aeolian modes foretelling the rise of major and minor tonalities.
Infinite Melodic Possibilities
Let the sequencer generate melodies imbued with the organic flow and spiritual resonance of early music, now reimagined for contemporary creativity. Whether sculpting ethereal soundscapes or exploring experimental forms, this device breathes new life into your compositions.
The project works perfectly for normal use of the FZ-1, FZ-10M and FZ-20M. All menu screens, editing pages, sampling functions, parameters and general operation display correctly. Only a few fully graphical screens, such as Hand Drawing, Sin Synthesis and Graphic Envelope, may show minor pixel irregularities. This does not affect usability in any way; these functions continue to work normally and the issue is purely visual. As I no longer have time to continue development, I do not plan to refine these small graphical details. Even so, the kit leaves the FZ fully usable, which is exactly what allowed me to bring my own FZ-1 and FZ-20M back to life and use them normally again.
FZ-1 Kit
For the FZ-1, we supply a complete kit, including: A dedicated support with the logic board. A second support with the new OLED display that fits perfectly into the original display mounting position.
Installation requires no soldering and no special skills. The kit uses the original FZ-1 mounting screws, and the entire installation can be completed in under 20 minutes. Please watch the FZ-1 installation video on our YouTube channel for a full step-by-step demonstration.
FZ-10M and FZ-20M Kit
For the FZ-10M and FZ-20M, we supply a single integrated assembly including the support, logic board and display. This assembly fits perfectly into the original display location of the module.
Installation is very simple, requires no soldering, and typically takes around 15 minutes. The process is also demonstrated in the installation video available on our YouTube channel.
Pricing and Ordering
The price for the kit (logic board, display, supports and cables) is US$249.00 + shipping.

"Up for sale is an original 1974 EMS Synthi 100 Synthesizer. I am the second owner of this amazing instrument. It is in incredible condition for an item of its age and size. Very few of these were produced in the early 1970s and most of them were sold to institutions, private studios and musicians - these almost never turn up for sale on the open market.
This particular Synthi 100 was one of the last produced by EMS (London) and has all of the standard factory updates including newer scope, sequencer memory display and patchable multimeter. below is a list of what is included with the auction:
"❄️ Alchemy Of Glacial Rhythms is a bank of 50 rhythmic presets for Xfer Serum 2, inspired by the north and its cold winters, which are accompanied by a special dark magic. The core idea of the bank was to create rhythmic, atmospheric, and "cold" sounds that evoke a certain magic. The result was brutal yet ethereal arps, growling basslines, magic pads, cold noisy synths, and mystical textures.
📦 Get these patches: https://antonanru.sellfy.store/p/seru... The bank includes 50 Presets: 10 arps, 10 basses, 10 pads, 10 synths, 10 textures. 👤 The author of the soundset is skendi (Arseniy Pushkov).
🔮 The soundset spans a wide range of tones, from warm, deep and atmospheric textures to clean, punchy, bright and airy timbres. The sounds include different combinations of oscillators in different modes, such as wavetable, FM, granular and spectral as well as different types of reverbs, delays, distortions, filters, and modulations. Presets are suitable for genres such as ambient, cinematic, IDM, experimental, techno, breakbeat, jungle and many others.
🎛 Macros can change tone, stereo width, modulation depth and rate, noise level, distortion, detuning, space/echo/reverb, effects mix, envelope parameters, and others. You may control them via MIDI controller, use them for automation, or map the macros to your DAW modulators like LFO, Shaper, and others.
ModWheel adds expressiveness to the timbre.
❗️Compatible only with Serum 2. Not compatible with Serum 1. Installation: Open the Serum menu and click 'Show Serum Presets Folder.' You will see folders containing different Serum content. Open the 'Presets' folder and place the new bank (folder) of presets there."
"Meticulously refurbished over approximately 22+ hours to be as good as it could possibly be, with a new set of modern faders that are way better than the originals and their copies, this unit is a real pleasure to play and is fully functional, with one exception - we disabled the guitar interface. This unit can still be controlled via CV and gate.
Why did we disable to guitar interface? This unit, like most, did not come to us with the guitar pickup and cable, so we weren't able to test it with a guitar. That said, the guitar interfaces are usually broken and beyond repair at this point. The manufacturer sealed the interface circuitry in epoxy, so if (and when) a component inside that black epoxied box goes bad, as they almost always do, they're impossible to open and repair by practical means. Also, even when the guitar interface is working, you'll need the pickup and cable, which have often disappeared over the decades. So, if you're looking for a unit that will work with your guitar, this one won't, and it's likely many others won't either, based on what we've seen - please search our listings to see if we have another in stock that does. This one contains the same synth engine as the ARP Odyssey Mk3 (with a couple very minor differences in the modulations) and can be controlled via a midi-to-cv converter or compatible vintage keyboard or sequencer. Be careful if you're considering buying one of these elsewhere - most sellers don't test them properly and don't know enough or care enough to identify and report problems, especially with the guitar section. Any avatar or odyssey that still has its original faders will almost definitely need them replaced, so consider that too. And then there are the ones that use the low quality copies of what were already low quality original faders. We already did this work, and it's expensive. Cost was around $300 for the new faders, plus additional parts, plus 22 hours of skilled labor, plus additional labor to route the sample and hold mixer output to modulate VCO2 and the filter for oscillator and filter FM as you'd have on an Odyssey (which is being performed as I type this so I don't know the total time yet)."
"🧿 Encrypted Pulse is a collection of 50 patches for the semi-modular synthesizer Behringer Grind. The bank includes: 11 Basses, 12 Leads, 12 Plucks, and 15 Chords. ⚙️ The centerpiece of Grind is its multi-mode oscillator — a powerful and flexible sound source capable of generating a wide variety of tones. This collection was born from an exploration of that oscillator’s potential in combination with the synth’s other sections and the patchbay.
🔮 In this collection, I aimed to create dark, noisy, gritty, and sometimes atonal presets suitable for genres such as techno, ambient, IDM, industrial, deep, house, progressive, downtempo, breaks, drum 'n' bass, and others.
"Very unique rare synth with interesting effects. In excellent working condition. It just has a minor dimple on the display surface which doesn’t affect the led lights at all and there is a small scratch on the corner. Comes with original power supply."
"#Elmyra2 v2.4 — What’s New and Improved Sound Engine
Higher sample rate and improved wavetable resolution → noticeably cleaner top end. New wavetables added. Overall mix saturation refined, with “soft” (122) now default. Knob value stability and tuning precision improved.
Filters New comb filter (codes 3321/3322). RESO = damping, CUTOFF = delay time, with optional pitch tracking. Ladder filter reworked — now true multimode (LP/BP/HP) with higher quality. Ladder LP (331) is the new default filter. State-variable filter retains LP/BP/HP modes (341–343) but with improved gain staging, resonance, and cutoff ranges.
Delay & Reverb Delay fully re-implemented → cleaner feedback, no lock-ups. Added proper reverb engine controllable with delay knobs. Code 441 = delay (default), 442 = new reverb, 4411 = legacy lo-fi reverb. TIME = decay, FDBK = color, MIX = blend. Dry/wet crossfade curve improved for smoother transitions.
Modulation New MODP: oscillator hard-sync (orange LED, position 5). MOD controls the synced oscillator pitch. LFO1 knob-motion recording (code 2413) — record live movement of LFO rate. Sequencer output to LFO1 possible (243v). Per-voice sequencer clock divider (11sv). Digitally controlled envelopes in multiple short modes (221v → very short … 224v → disable). Detune MODP range expanded.
Scales & Chromatic Mode New musical scales for chromatic mode: major, minor, major pentatonic, minor pentatonic (CHRM + 11–14). Scale selection now unified under the CHRM button. Knob-to-pitch mapping in chromatic mode is now linear and exact.
User Interface & Workflow
LED feedback overhaul — REC and PLAY flash to confirm code entry, sequence record, mute, and drone states. Quick mute/unmute voice (MODP + PG long press). Quick octave switch (MODP + double-tap PG). Pink MODP LED at startup identifies firmware 2.4. Touchpad LEDs more reliable during operation. Drone and mute response feels snappier.
Under-the-hood Fixes State-variable filter crash fixed (previously triggered by fast cutoff modulation). Improved detune, filter, and delay behaviors under modulation load. Sequencer timing more consistent with internal clock."

"This is a unique opportunity to buy a monster synth, that is also a piece of synth pop history. Two cabinets plus the original keyboard, all lids, interconnection cables and original manual included. The first cabinet is a Roland System-700 Lab is one of the rarest and most sought-after modular synthesizers ever built.
Introduced in 1976 as part of Roland’s legendary System-700 series, the Lab version was designed as a compact, self-contained modular laboratory for advanced sound design, research, and education — but with the same discrete analog circuitry, massive sound, and build quality as the full studio system.
This one was owned by Bill Vorn, keyboardist of the synth-pop band Rational Youth, used in the following albums dated 1981 to 1983 : Rational Youth, Saturdays in Silesia, City of Night and I want to see the light, as reported in the certification signed by Bill Vorn himself, provided in the item. The second one is another original SYS 700 one, connected and internally cabled to the main one by means of the original cable, with the super rare modules that you see in the picture: an additional, multimode filter, the great output module and… a professionally custom module with a perfect ARP 2600 VCF clone… plus other stuff.
All the best Sys 700 modules, featuring the iconic vintage Roland tone — warm and incredibly dynamic — and offers an extraordinary range of sonic possibilities thanks to its flexible patch architecture. Perfect for collectors, professional studios, or synth enthusiasts looking for a centerpiece instrument with historical and musical significance. The system sports a comprehensive modular architecture with 3 oscillators, 2 filters, 2 VCAs, 6 envelopes (!), mixer, phaser, spring reverb (HUGE) and …utilities.
Legendary System-700 sound — powerful basses, evolving textures, experimental tones. What to say more? Fully functional and in very good cosmetic condition with minor signs of use. You will never find another in such condition. Last call…"

"Pretty good condition considering how old it is - the endcheeks have the usual minor damage on the corners but the panel, knobs, keys etc are very good. It needs a litle work* to be 100%: it has probably about 4 duff keys (will need re-coating with the special compound you can get) otherwise works over CV, Internally from what I remember, it has a slight crack on the pcb which had been patched up and resoldered by the previous owner. Few noisy pots etc."
