Message: [QUOTE="Bombastus, post: 91965, member: 2178"] FL Studio’s Sampler keeps a one-shot playing after note release unless you enable its Volume envelope. A short Piano Roll note can therefore trigger the entire 808 sample even though the block on screen ends much earlier. Cut Itself does not solve this particular problem because it waits for another note to arrive. It is useful for [B][URL='https://goldmidi.com/community/resources/how-to-stop-808s-from-overlapping-in-image-lines-fl-studio.58/']preventing consecutive 808 hits from stacking[/URL][/B], but note length is controlled by what happens when FL Studio receives note-off. If you want the bass to stop when the drawn note ends, the sampler needs an amplitude envelope that responds to that event. [HEADING=2]The Volume envelope makes note length matter[/HEADING] Open the 808 from the Channel Rack and switch to the Envelope and Instrument settings. Select Volume, turn the envelope on, keep the attack at zero, set sustain to full, and bring release down to zero or very close to it. With the level held at full sustain, the sound remains open while the Piano Roll note is held and falls when the note ends. The important control is not Hold by itself. Many tutorials tell you to push Hold to maximum and turn everything else down, which can work for common one-shot setups, but it hides what the sampler is actually doing. Sustain determines the level maintained while a note remains active, while Release determines how long the sound continues after note-off. A [B][URL='https://doi.org/10.3389/frsip.2023.1284100']formal ADSR amplitude envelope model[/URL][/B] treats note-off time and release time as separate parts of the envelope. FL Studio follows the same practical distinction. The right edge of a Piano Roll note sends the release event, then the Release control decides whether the 808 stops immediately or fades beyond that edge. Zero release gives you the tightest possible timing. A tiny release can sound less abrupt on some 808s, although it also means the audible bass extends slightly beyond the note block. You are choosing between an exact hard stop and a short fade, not changing the musical length of the note itself. Attack and decay also change the shape before note-off. For a typical 808 one-shot that should hit at full level, a zero attack avoids softening the front, while full sustain prevents the envelope from fading toward silence during a longer held note. Decay matters much less when the sustain level is already at maximum. [HEADING=2]Long Piano Roll notes cannot create missing audio[/HEADING] Envelope control can shorten a sample, but it cannot manufacture audio after the source file has finished. If your 808 file lasts one second, drawing a four-second note does not automatically stretch that waveform to four seconds. The sampler reaches the end of the file and has nothing left to play. This catches people after they fix the opposite problem. Short notes suddenly behave perfectly, yet long bass notes still die early. The envelope is working. The underlying 808 is simply shorter than the MIDI note asking it to continue. Loop points are one way around the limit. When a sample contains usable loop points and Use loop points is enabled, FL Studio can repeat the looped region while the note remains held. A smooth loop can extend a stable sub tail without changing the Piano Roll workflow, although a badly chosen loop boundary may sound obviously repetitive. Time stretching is another option when you need a longer fixed sample rather than a repeating sustain. It changes the audio itself, so it solves a different problem from the Volume envelope. Pick the method according to whether you want the existing tail extended, a region sustained, or the original one-shot left untouched. [HEADING=2]Sampler settings do not control every 808 source[/HEADING] The Channel Sampler envelope applies when the 808 is loaded as a sample in FL Studio’s Sampler. An 808 generated inside a synth or third-party plugin can have its own amplitude envelope, and the plugin may ignore the Sampler controls you expected to use. In that case, adjust the instrument’s own sustain and release behavior. Audio placed directly on the Playlist is different again. A Playlist Audio Clip is arranged as audio rather than triggered as a Piano Roll instrument note, so dragging MIDI note lengths is not part of its playback logic. Trim the clip, fade it, or load the sound into the Sampler if you want Piano Roll note-off to control it. One quick test exposes which problem you actually have. Draw one long 808 note followed by silence, enable the Volume envelope, then shorten only the right edge of the note. If the audible stop follows your edit, note-off control is working. If the sound still ignores the edit, check whether you are really using the Channel Sampler or whether the sound is coming from a plugin, looped source, or separate audio clip. [/QUOTE]
