Born of the imagination of world-renowned keyboardist Jordan Rudess and the software engineering excellence of French audio developer BLEASS, SampleWiz 2 is a unique and powerful S&S (sample & synthesis) instrument. BLEASS SampleWiz 2 combines modern features such as granular and cloud sample engines, MPE, and iOS/desktop interoperability, with the satisfying, rapid workflow of classic hardware samplers. Capture any sound, import your own samples, and transform them into playable instruments in just a few gestures. Granular and cloud-based sound engines, slicing, modulation assignment, filtering, envelope shaping, drive, and integrated effects provide powerful yet immediate tools for sculpting sounds ranging from subtle textures to entirely new sonic landscapes. Full MPE support (Slide and Pressure) enables deeply expressive performances, giving every gesture a direct impact on sound and allowing nuanced control over dynamics, timbre, and movement. Designed for touch from the ground up, SampleWiz 2 combines powerful sampling and synthesis capabilities with an intuitive workflow that keeps experimentation fast, interactive, and musical.

About

DelayCalc BPM

Features
Read full description

Type one tempo and every time-based value for that song comes out at once. Delay times, LFO rates, reverb tails, loop lengths in odd meters, the key after a tempo change, and sample counts. No reopening a second calculator. Dark enough to read in a studio, and every value copies with a tap. ■ Delay & LFO Enter a BPM and every note value lines up with its delay time in ms and its LFO rate in Hz. Straight, dotted and triplet, plus 5- and 7-tuplets (5:4 / 7:4). Tap a note value for seconds and sample counts at 44.1 / 48 / 96 kHz. It goes the other way too. Enter the ms or Hz you already have and get the BPM back, with the closest note values listed — so "what tempo is this pedal's 375 ms" takes one entry. ■ Reverb Pre-Delay and Total Reverb Time from the tempo, with Decay and where the tail lands. Then Tail Clearance: whether the tail ends before the next hit, and by how much. Clear, overlapping, or exactly on it — as a number rather than a guess. The basis is stated on screen: Total Reverb Time includes Pre-Delay, quarter-note basis. Plugins define Reverb Time differently, and that is on screen too. ■ Tempo & Key From a sample's original and target tempo: Tempo Change, Playback Speed, Semitones and Cents. Then the key it lands on, in Camelot Key and Open Key, with the Harmonic Matches worth mixing into. Preserve Key (Master Tempo / Key Lock) treats the key as unchanged. Enter the original duration and you also get the new length, its sample count, and how it fits into bars. ■ Loop Length Bar and loop lengths from a time signature (3/4, 5/4, 5/8, 6/8, 7/8, 9/8 and more) in ms, seconds, Hz and sample count. Or the other way: give it a length and get the tempo. ■ Library Keep the setups you use, named, up to 50. Restoring brings back the page and the time signature, so you carry on where you were. ■ Where it earns its place · Setting delay and LFO values in a DAW · Keeping a reverb tail off the next hit · Matching a delay pedal or hardware synth to the tempo by hand · Getting the BPM and note value back from ms or Hz you already have · Loop lengths in odd meters, and sequencer rates · The key a sample lands on after a tempo change · Lining effects up to tempo at a rehearsal or a live set ■ What it does and does not do · Values use the project tempo, quarter-note based, so they match your DAW · Reverb and delay tails are starting points. Set the final value by ear, to suit the source and the gear · No microphone analysis, no DAW integration. You type, it answers ■ Quietly dependable · Saved setups stay on the device. Nothing is sent to a cloud · The core calculation works offline. Only the privacy policy opens a connection · No account · No ads · No subscription. One purchase · iPhone, iPad and Mac on that one purchase ■ Note values 1/1, 1/2, 1/2D, 1/4, 1/4T, 1/4D, 1/8, 1/8T, 1/8D, 1/16, 1/16T, 1/16D, 1/32, 1/32T, 1/32D Advanced: 1/4 (5:4), 1/8 (5:4), 1/16 (5:4), 1/4 (7:4), 1/8 (7:4), 1/16 (7:4)
