In Depth

After the overwhelming success of Bundle A, one thing became clear: the world needed more AlexKid sequencing magic. Sequencer Bundle B delivers exactly that—three more inspirational MaxforLive sequencers (plus a bonus device) that expand your creative possibilities while maintaining the analog-inspired workflow that made the first collection legendary.

This “Bravo Edition” builds on Bundle A’s foundation with tools specifically designed for parameter automation, classic acid basslines, and rhythmic texture. Whether you’re sequencing filter sweeps on external hardware, crafting authentic TB-303-style acid lines, or adding human-feeling handclaps to your productions, Bundle B provides the surgical precision and happy accidents that define AlexKid’s approach to music creation.

The Collection

Empirical Sequencer – The Cute Little Sequencer Evolved

What happens when you take the beloved Cute Little Sequencer and supercharge it? You get Empirical Sequencer—a 16-step powerhouse that keeps everything you loved about its smaller sibling while adding sophisticated parameter control for unprecedented creative flexibility.

Empirical maintains the core philosophy: three independent sequence lines (gate, pitch, and parameter control), each with adjustable length (1-16 steps) and four play modes (forward, backward, bidirectional, random). The pitch line still forces notes into your selected key and scale—using the Push 2 scale library—ensuring randomization stays musical. Clock division, swing, and note length controls remain immediately accessible.

The game-changer is the third line. Where Cute Little Sequencer featured velocity control, Empirical replaces this with a parameter control line that opens entirely new creative dimensions. Two versions are included to match your workflow:

Parameter Edition: Features a Live Parameter Control line assignable to any parameter in Ableton Live. Sequence reverb sends, filter cutoffs, compressor thresholds, plugin parameters—anything you can map within Live becomes sequenceable. Create evolving effect sequences that phase against your melodic patterns, or use the line independently to automate single parameters over complex polyrhythmic cycles.

MIDI CC# Edition: Features a MIDI Control Change line assignable to any CC# on your sequencer’s MIDI channel. Perfect for external hardware synths and drum machines. Sequence your Moog’s filter cutoff, automate your modular system’s VCA, or create evolving timbral changes on vintage gear—all synchronized to your Ableton session. Min and Max values let you attenuate or reverse the intensity, preventing extreme parameter jumps.

Both versions feature the advanced mode toggle between step and gate modes. In step mode, all lines advance with the clock division. In gate mode, the pitch and parameter lines only advance when gates trigger—creating intricate polyrhythmic relationships between rhythm, melody, and timbral evolution.

The polyrhythm capabilities shine when you set different line lengths. A 5-step pitch sequence against a 13-step parameter line against an 8-step gate creates patterns that evolve over bars, even minutes, before repeating—perfect for live performance and generative composition.

Press4Acid – Pure Analog Bassline Heritage

If you’ve ever craved the sound of a TB-303, yearned for that squelchy acid bassline magic, or wished you could capture classic analog sequencing behavior in Ableton Live—Press4Acid was designed for you. This is an 8-step sequencer laser-focused on one thing: crafting perfect acid basslines.

Four independent sequence lines define your bass sound: gate (rhythm), pitch (melody), accent (dynamics), and glide (portamento). Each line features adjustable length (1-8 steps) and multiple play modes, enabling the polyrhythmic sequences that define great acid music.

The gate line defines your rhythm with clock division defaulting to 16th notes—perfect for that driving acid pulse. Swing and note length controls add groove and pocket. The pitch line creates your melody, forced into your selected key and scale to keep randomization musical even at maximum chaos.

Here’s where Press4Acid channels its analog ancestors. The accent line controls which steps receive emphasis, with separate velocity values for accented (Val Hi) and normal (Val Lo) steps. This mirrors the behavior of classic analog sequencers where accent adds punch and presence to specific notes. The glide line determines which steps trigger your synth’s portamento, creating those signature sliding notes that define acid music.

Note: Your synthesizer must be monophonic and feature a glide/portamento function for the glide line to work. The sequencer is perfectly matched with instruments like the Roland TB-03, Native Instruments Monark, Ableton’s Analog, and countless hardware monophonic synths.

The advanced mode toggle switches between step and gate modes, fundamentally altering how the sequencer behaves. In gate mode, pitch, accent, and glide only advance when gates fire—creating complex evolving patterns from simple programmed sequences.

Individual randomization per line plus the “Press4Acid” global randomization button (optimized for musical results) deliver instant acid inspiration. Can you pass the acid test? With Press4Acid, you’re already halfway there.

Clap Machine – Disco Soul in a Box

Every track needs texture, and every groove benefits from human-feeling rhythmic elements. Clap Machine is a specialized device that generates unique, organic handclaps—automatically sequenced or MIDI-triggered—bringing disco soul and human feel to your electronic productions.

The device features Auto-Play Mode, which automatically triggers claps on beats 2 and 4, just like a real drummer or disco band. But this isn’t a static sample player—the timing can be loosened or tightened to emulate the natural variation of real hand-claps, where multiple people never quite hit at exactly the same moment.

This subtle timing variation creates the warm, organic feel that separates human-performed claps from rigid programmed samples. The result sounds alive, breathing, natural—even though it’s generated by an algorithm.

Beyond timing, Clap Machine provides comprehensive sound shaping: control the character, tonality, and stereo imaging of your claps. Want tight, focused claps for techno? Wide, airy claps for deep house? Dark, aggressive claps for industrial? The controls provide surgical precision over the sonic character.

While Auto-Play handles the basics, you can also trigger claps via MIDI for complete rhythmic control. Layer Clap Machine with Hats4Dayz from Bundle A for completely organic-feeling rhythm sections that breathe and groove like live performances.

Unified Workflow

Bundle B maintains AlexKid’s signature design principles while expanding into new territory:

• Analog-inspired interface – Immediate control without complexity
• Intelligent randomization – Optimized algorithms keep results musical
• Forced scales – Pitch lines locked to selected keys for instant usability
• Polyrhythmic architecture – Independent line lengths create evolving patterns
• Multiple play modes – Forward, backward, bidirectional, and random
• Full Push 2 mapping – Hands-on control without mouse diving
• Step vs Gate modes – Fundamental behavioral changes for creative flexibility
• Hardware integration – MIDI out to external synths and machines

Creative Applications

Use Empirical Sequencer (Parameter Edition) to create evolving reverb tails that phase against your melodic patterns, or sequence a compressor’s threshold for rhythmic pumping effects. Deploy the MIDI CC# Edition to automate your modular system’s parameters or sequence your vintage synth’s filter while maintaining perfect sync with Ableton.

Route Press4Acid to a monophonic synth—hardware or software—and instantly generate squelchy acid basslines with authentic accent and glide behavior. The randomization functions provide instant inspiration when you need that perfect 303-style sequence.

Add Clap Machine to your drum bus for organic handclap textures that breathe with your groove. The timing looseness creates the human feel that separates great electronic music from robotic loops.

Combine Bundle B with Bundle A for a complete sequencing ecosystem: use Coin Locker Babies for ambient pads, Empirical for evolving filter sweeps, Press4Acid for driving basslines, Hats4Dayz for hi-hats, and Clap Machine for organic rhythmic texture. Each device contributes its unique voice while maintaining AlexKid’s cohesive design language.

How to Use

Drop Empirical Sequencer onto a MIDI track—choose Parameter Edition for internal Live control or MIDI CC# Edition for hardware. Map the parameter or CC# line to your target (filter, reverb, modulation), then program or randomize your sequences. Use different line lengths for polyrhythmic parameter evolution.

Route Press4Acid to any monophonic synth with glide/portamento. Select your key and scale, then either program patterns manually or hit the randomization button for instant acid inspiration. Experiment with gate mode for evolving glide and accent patterns that shift against your bass melody.

Insert Clap Machine on an audio or MIDI track. Enable Auto-Play for automatic 2 and 4 claps, or trigger via MIDI for custom patterns. Adjust timing looseness for human feel, then shape the character and stereo width to fit your mix.

All devices feature the on/off toggle for muting while keeping sequences running—essential for arrangement work and live performance. Full Push 2 mapping enables tactile control without interrupting your creative flow.
