Percussion synthesiser module reverse-engineered from the original TR-909 circuit - 8HP wide
Notes: Reverse-engineered from the original machine, our BD909 is an identical recreation of the original all-analog drum circuit of the TR-909. We've added additional controls and synthesis features that turn this classic circuit into a chest-pounding analog bass drum laboratory - all tightly packed into an 8HP module. The BD909 sound differs from our BD808 in that the main sonic energy is centered in the mid to low frequency range (as opposed to the low frequency range of the BD808). This frequency range gives the needed headroom allowing your bass Lines to deeply fill up the low end while the kick drum rides on top - creating a clear and punchy mix.
The BD909 includes all the controls found in the original: Attack, Decay, Tune Decay, Accent and Level. We have gone beyond that and added controls that further increase the palette of sound this circuit is capable of. First off, we've added a tuning control knob for the oscillator and included its own CV input and attenuator that let you tune your 909 kick with your bass lines. Next, we added control knobs for the tuning attack and extending tuning decay - each one affects the other, allowing for very intuitive and interactive sound shaping - this feature opens up numerous "sweet spots", and provides the ability to center the energy peak at different parts of the sound. Finally, we offer additional punch and distortion by giving complete control over the internal waveshaper, which allows you to overload the waveform manually or with voltage control.
Beginning with the classic and pure sound of the 909 kick, these additional functions greatly expand the BD909's flexibility and let it create powerful analog bass drums that range from soft and smooth to punchy and aggressive - and everything in between.
Hi-hat percussion synth module made from the legendary TR-808's closed & open hi-hat circuits - 8HP wide
Notes: Introducing the HATS808, part of Tiptop Audio's new series of drum modules that bring analog percussion into the modular synth world, instantly turning your system into a self-contained music machine.
The HATS808 is the TR-808's real, analog closed and open hi-hat circuits adapted for use in Eurorack modular synthesizer format and tested to sound just like it did back in the 80's. Adapting to modular foramt has allowed Tiptop Audio to add some special features for each voice, like independent accent levels, a high-powered gain stage, and a dual-input pulse-shaper. Filter Q and VC-Q knobs were added to the main band-pass filter for additional tuning and to allow you to generate crushed tones and self-oscillation at the knob's max position - all without comprimising the signature sound of the TR-808 hi-hats.
The HATS808 sizzling sound is made using six analog square wave oscillators mixed and processed by band-pass filters. This multi-oscillator design is what give the 808 hi-hat sounds their unique metallic character and akes each HATS808 sound slightlty different from one-another. The original "choke" circuitry that makes it sound so dynamic and tight is fully implemented, just like the original, but can also be disabled if needed, by disconnecting the internal connection between the two hats.
Just like the other drums in this series, the HATS808 high-powered output gain stage allows you to further harmonize the sound using distortion and clipping. On each input, there is a dual pulse-shaper circuit so you can trigger your HATS808 with Trigger/Gate signals from step sequencers, clock dividers or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module and ensures the same stable sound at peak power, regardless of your pulse source. All these unique features make integrating this legendary sound generator into your modular synth easy, unleashing the power of real analog drums.
Percussion synth module with TR-909's original closed and open hi-hats circuits adapted for use in Eurorack modular synthesiser format - 8HP wide
Notes: Introducing the HATS909, part of our new series of drum modules that brings those classic percussion sounds into the modular synth world, instantly turning your system into a self-contained music machine.
The HATS909 is the TR-909's original Closed and Open Hi-Hats circuits adapted for use in Eurorack modular synthesizer format and was tested to sound like a machine coming fresh off the assembly line back in the 80's Improving on the original, we have added some great new features that expand the sound palette of hats that can be produced with this small, powerful module.
The original TR-909 circuit is made with a combination of low-fi 6-bit sound samples that pass through a series of analog elements to provide envelope and filtering to the source sound. The HATS909 module allows for manual and voltage control of the sample's tuning, which provides anything from crushed hats and short ticks to the original sound and anything in between. A modulation switch allows you to tap a voltage control to either the tune input or the internal VCA for modulation with external control signals or for adding AM or FM synthesis in the audio range from external oscillators, other drum sounds, or just about any sound source. HATS909 also offers a switch for a direct tap to the output of the original sample, bypassing all other internal analog processing, giving you the pure source sound for synthesis any way you want with your own modules.
Just like the other drums in this series, the HATS909 high-powered output gain stage allows you to further harmonize the sound through distortion and clipping. On each gate input, we have designed a dual pulse-shaper circuit so you can trigger your HATS909 with trigger/gate signals from step sequencers, clock dividers, or any other pulse/clock sources.
Notes: ONE brings organic sound and super low latency sample playback to the modular. It differs from other sample players in that it handles the digital audio bits as a continuously manipulated electrical flow, a feature inspired by our analog knowhow. This unique core makes ONE truly integral within the Tiptop percussive modular ecosystem thanks to a lightweight and responsive digital circuit with a very analog feel.
ONE brings a world of colours to the modular right out of the package. We have invited some of the best sound designers in the Industry to create professional sound libraries with content tailored to the unique sonic framework of the modular synthesizer and that fully takes advantage of ONE's unique qualities. To start with, ONE comes with a SD card loaded with a free set of 60 sounds designed by Glitchmachines. More cards are available to purchase separately each containing carefully selected material with up to 256 sound files. Using your own sample libraries or recordings is easy too, just copy 16 or 24bit mono WAV files onto the SD card, pop the card into ONE and go.
ONE offers several modes of operation, with the primary being the super low latency Trigger mode that retrieves audio data off the SD card adding no artificial processing such as click removal, crossfading, EQ or gain normalization. In this mode, it's a highly transparent player up to 24 bit 96kHz with no interpolation of the audio data: what you put in is what you get out. With a delay as low as 0.25ms from the moment the trigger hits, ONE offers harmonically dense, clear and detailed audio with a great rhythmic feel.
ONE handles external CV through a user selectable multifunction jack. Pitch is the main control with two modes available: Free pitch allows for fine tuning of the playback rate, great for adding subtle vibrato or wild tape speed effects; Quantized pitch maps CV to the standard 12 tone system over 3.5 octaves and is ideal for melodic content. CV can also be used to sequence through files off the SD card allowing far more varied sounds from a single source; almost like an entire percussion section behind the slim panel.
Although originally designed to play tightly with our analog drums and envelopes, ONE's rich sound quality encouraged us to make it work in a variety of other applications that are less demanding of sub millisecond timing response. The extra headroom at the core level allows features such as Gated playback, Looping, and Triggering with fades in and out to accommodate different types of sound sources from drum loops to polysynth chords to noise sources and other yet unimagined uses.
ONE offers another useful dimension since it can play CV signals too. Drop in a card with LFO signals, random CV, slopes and envelopes for a whole set of new control and modulation possibilities.
ONE is as simple to use as it is affordable and plays extremely well with its analog cousins - our vision for bringing samples into the modular world.
Notes: The SD909 adapts the iconic TR-909 snare drum and noise generator for use in the Eurorack modular synthesizer format. We painstakingly tested the module in our lab to sound like a fresh machine coming off of the assembly line back in the 80s. On top of the original circuit, we have added new features that expand the palette of what can be produced with this analog circuit.
The sound of the SD909 consists of two main sections: the binary noise generator and two modulated triangle oscillators. The oscillators provide the low end punch while the noise makes up the upper sonic spectrum, resulting in a combination that makes the 909 snare sound so rich. In the SD909 module the noise generator and oscillators are variable and voltage controlled, which pushes the circuit beyond its original boundaries offering new sounds as well as many variations of the original tone. The panel has markings to guide setting the knobs to reproduce the snare sound of the vintage machine.
Just like the other drums in this series, the SD909’s high-powered output gain stage allows further enhancement of the sound through distortion and clipping. We have designed a dual pulse-shaper circuit on each gate input so you can trigger your SD909 with Trigger/Gate signals from step sequencers, clock dividers, or any other pulse/clock sources. Also, the SD909 is equipped with access to the MIXZ MixBus matching the rest of the Tiptop line of percussive modules.
8HP voltage-controlled ADSR envelope with CV processor - 'New Style'
Notes: The Z4000 NS is a snappy voltage-controlled analogue envelope generator with a built-in CV processor for scaling, inverting, and voltage-controlled deviating of the envelope shape. The Z4000 generates an envelope made of the four classic segments: Attack, Decay, Sustain and Release, in which each segment can be manually set using knobs or dynamically set under voltage control.
Control knobs for the Attack, Decay, and Release segments are scaled. The first 0-50% of the knobs rotation is dedicated to high resolution adjustment in the millisecond range.
The output levels are fully adjustable with signals that can reach up to 10V in either polarity and can be mirrored into the opposite polarity or clipped using the voltage-controlled deviater-scaler. A bi-colour LED indicates intermediate values in both polarities and their crossfade state.
The Attack slope switch allows selection of a logarithmic or exponential curve for the Attack segment. This subtle effect helps further the fine adjustment of the Attack segment slope. A Shoot button is provided to let you fire the envelope manually. The Z4000 also provides a retrigger input allowing you to create legato notes when using a classic keyboard interface.
Going down to nuts and bolts, the Z4000's smoothness and snappiness is made possible by a four-segment active-charge discrete circuit which is an extended version of circuits found in classic two-segment rise/fall transient generators.
