KQ Sampei Legacy vs GSDSP Quantum Filter

### THIS IS A DEPRECATED PRODUCT. Get KQ Sampei 26 instead. ### If you bought this app recently, you can request a refund. A sampler synthesizer which sound sets can be changed. It is multi-timbral. Available Sound Set Formats: Sound Font(sf2), Compressed Sound Font(sf3), Downloadable Sound(DLS) Supports a part of common MIDI messages (GM, GS, XG, MPE). Includes a MIDI File Player. It supports Standard MIDI Files and RIFF MIDI Files. It also supports multiple ports and loops. Supports external storages. DO NOT USE ON-DEMAND LOADING WITH SLOW STORAGES SUCH AS HDD, USB STICKS, SD CARDS. You can customize sound sets with "Modifiers". In default, a modifier which adds soft pedal function, and GS Custom Controller mod are being applied. You can select "Original" and disable GS Custom Controller if you want. Supports Audio Unit v3 and Inter-App Audio. You can use this synth as a plugin for another app such as GarageBand, AUM, Cubasis, etc... To maximize compatibility with other SoundFont players such as FluidSynth, select the engine V3, turn off "Custom GS Controllers", "Slow LPF", "Smooth Volume Level". Supports Micro-tuning. Place AnaMark TUN files into Tuning folder. You can use sound sets as long as the device memory allows. The actual memory limit seems to be around the half of the hardware RAM. Not that the limit of Audio Unit is much smaller. You may be able to load sounds over the memory size if you turn on "Load On Demand" (Streaming load). In the developer's environment, 4.2 GB of SoundFont could be loaded on an iPhone with 1 GB of memory. You can play this app with external MIDI devices and Virtual MIDI apps. URL Scheme: kqsampei:// Includes a sound set, "GeneralUser GS v1.471" by S. Christian Collins. I prepared modifiers for this set. This app developer does not collect any user information other than what is collected by iOS/iPadOS. This app and the description contain machine translated text.

Analog warmth meets flexible routing and dynamic modulation in a filter workstation built for creative sound design. Analog-Modelled Filters Quantum Filter uses resonant, analog-modelled filter designs that behave smoothly and musically across the entire spectrum. With no cramping, stepping, or digital artefacts, the filters remain stable even under rapid modulation. At high resonance settings they can reach self-oscillation, similar to classic hardware circuits. Filter Types & Routing Choose from 11 filter modes, including Lowpass, Highpass, Bandpass, Notch, Shelving options, Bell, and Ladder Lowpass in 1–4 pole configurations. Combine filters in series (up to three stages) or parallel (up to two), resulting in over 2,000 possible routing combinations for detailed tone shaping and complex layered filtering. Built for Modulation Designed to handle fast, artefact-free modulation, Quantum Filter responds cleanly even under rapid parameter changes. Its stability makes it suitable for dynamic environments, rhythmic modulation, or complex movement across multiple filter stages. Stereo and Dual Mono Switch between stereo and dual mono modes to shape the stereo image. In dual mono mode, left and right channels can move independently, enabling asymmetric movement, wider imaging, or separate modulation paths for each side. MIDI Control Quantum Filter integrates ADSR & AR modulators that respond directly to MIDI, allowing envelope-driven filter motion that behaves like a synthesizer’s filter section. This integration adds expressive control for rhythmic gating, animated sweeps, and dynamic shaping based on your playing or sequencing. Quantum Filter is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
