Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves. Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones. Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space. Features: - Orbital echoes, where Feedback sets how many circle you - Spin, from a gentle drift to a full whirl - Doppler pitch-bend as the orbit turns - 3D binaural imaging for headphones - Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves) - Per-echo Trail tone, tape Wobble, and Drive - Lush reverb applied to the echoes - Full 5-band EQ on the wet signal - Orbit and Ping-Pong patterns, tempo sync - 18 factory presets, plus save your own - Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more No accounts, no tracking, no data collected. Everything stays on your device.

Play 12 traditional Chinese instruments, record a phrase, shape your audio, and continue in a compatible AUv3 host. A breath moves through bamboo. A fingertip wakes a silk string. Bronze rings, a drum answers, and a melody begins. BambooSilk was created for that first musical moment—when an idea is still small, immediate, and alive. Touch the instrument, follow the phrase, record it, then carry it into a larger production without leaving its character behind. FROM ONE TOUCH TO TWELVE INSTRUMENTS Open the app and begin playing. Twelve traditional Chinese instruments are arranged in four families: • Strings: Guqin, Guzheng, Yangqin • Winds: Dizi, Xiao, Suona • Plucked: Pipa, Zhongruan, Sanxian • Percussion: Tanggu, Bianzhong, Paigu Each instrument has its own performance surface. Play multiple notes at once, move between techniques, change octave, and capture a take directly from the portrait interface. Connect a USB MIDI keyboard or pair a Bluetooth MIDI controller to play the selected instrument with velocity, sustain, and pitch bend. A quiet Guqin phrase, a bright Dizi line, a rapid Pipa figure, or the pulse of Paigu can all begin beneath your fingers. LET A RECORDING FIND ITS SPACE Sometimes the story begins outside the app. Import a WAV, AIFF, M4A, or MP3 recording from Files and see it unfold across the waveform. Scrub to the exact moment, listen before and after, then shape warmth, tone, stereo width, echo, resonance, and wet/dry balance until the performance sits naturally in its own space. Your installed AUv3 audio effects can join the same workspace. Scan compatible effects, switch plug-ins, compare with bypass, open a plug-in’s native interface, or use a generic parameter view when needed. TAKE BAMBOOSILK INTO YOUR HOST The standalone app is only the beginning. Three included AUv3 tools let the same musical language continue inside a compatible production host. BambooSilk Effect Give an audio track warmth, tonal shape, stereo space, echo, and a natural tail. Ducking keeps the original performance clear while the effect returns between phrases. Parameters support host automation, preset recall, Mix Lock, A/B comparison, bypass, and state restoration. BambooSilk Instruments Perform all 12 included Chinese instrument timbres from MIDI. It supports 16-voice polyphony, sustain, pitch bend, performance techniques, and an on-screen audition keyboard. Use the MIDI modulation wheel for expressive vibrato on Dizi, Xiao, and Suona. BambooSilk MIDI Scales Turn incoming notes toward Gong, Shang, Jue, Zhi, or Yu pentatonic modes. Choose the root and target instrument, then shape transpose, quantize strength, velocity, timing, variation, and note probability. The chosen instrument can travel downstream through MIDI Program Change. A COMPLETE PATH FOR A MUSICAL IDEA Begin with touch. Save the performance. Refine a recording. Then continue arranging and automating in compatible hosts such as GarageBand, Logic Pro, Cubasis, and AUM. AUv3 availability and routing options depend on the host. An interactive in-app guide helps you get started with touch performance, USB/Bluetooth MIDI, audio polishing, and plug-ins. From bamboo breath to silk resonance, BambooSilk gives traditional colors a place in a modern music workflow. Supports English, Simplified Chinese, Traditional Chinese, Japanese, Spanish, and French.

Verdict
The clearest difference is update cadence: BambooSilk at daily against Seyfert's every 2 days. Seyfert's advantage is price ($1.99 vs $3.99) and iOS requirement (15.0 vs 17.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
