Studio Flow
Any Idea Becomes a Song with Your Fingertips.
Your free online beat maker is already a complete studio. Start with a drum pattern, click in a melody, then drag pitches and note lengths with your fingertips. Choose a scale and keep the idea in key. The sequencer-based Studio Flow is the fastest way to create new beats.
- 01Click-to-Beat Step Sequencer
Click steps to place kicks, snares and hats. Extend the pattern when the groove needs more room.
- 02Intuitive Melodic Step Sequencing
Tap a rhythm, drag notes up or down for pitch and stretch note lengths. Choose your key and scale; Spider keeps the notes in tune.
- 03The Power of Part-Based Structure
Shape an Intro, Verse, Build or Drop independently. Jump into Arrangement or use Free mode when the idea needs total freedom.
- 04Watch the Clip Write Itself
In Part Locked mode, steps write directly to the active Part's MIDI clip. The same notes are already waiting in Arrangement.
Watch the clip write itself
Every step is already part of the song.
In Part Locked mode, the sequencer writes straight into the active Part's MIDI clip. Move to Arrangement and the kick, snare and hats you just created are already there — ready to shape from either view.
- Nothing to export
- No duplicate pattern to maintain
- One set of notes, two ways to shape it
Structure when it helps. Freedom when it does not.
Copy a finished Part and the next variation is already halfway there. Or switch a track to Free mode, follow the unexpected idea, and bring it into the song when it feels right.

A great arrangement evolves. Record instrument and effect parameter movements while the track plays, then shape their automation in the timeline. Build filter rises, changing textures and expressive effect transitions around the music—not around a separate file.
Turn exposed synth and effect controls during playback with automation recording enabled. Your gestures become editable parameter changes in the project.
Edit automation points and curves in Arrangement. Control where a filter opens, an effect builds or a sound settles back into the next Part.
Combine MIDI variations, Song Parts and parameter automation to create tension, release and movement. Keep developing the same project from Studio Flow through Arrangement and mixing.

Online DAW · answered
A browser studio that goes beyond sketching ideas.
Spider Neural Ultra is an online DAW for making complete tracks: sequence the first beat, shape MIDI and audio, build the Arrangement, mix and export — without leaving the production workflow.
Can I join the beta and use premium production features for free?
Yes. Create a free Spider account to join beta testing and explore premium production tools. AI usage is limited, and the optional desktop VST3 Bridge is available on request. Future Pro plans and pricing are separate from beta access.
How can I make a beat online without downloading a DAW?
Open Spider Studio Flow in your browser. Choose a drum machine, click steps to build the beat, then add bass, chords and a melody. All 13 built-in instruments and MIDI devices belong to the same editable project in Arrangement.
What makes Studio Flow different from standard DAW sequencers?
Click steps to program drums, drag melodic notes up or down for pitch and stretch their lengths. Combine this with modular Song Parts. In Part Locked mode, Studio Flow writes standard MIDI clips directly into Arrangement: one set of notes, two ways to shape it.
How does Spider AI differ from other AI music generators?
Spider AI creates white-box, fully editable DAW data instead of flattened audio. Generated clips, Parts and song ideas contain separate tracks, MIDI notes and real instrument parameters. Preview the result, apply what you want, then edit, replace or automate it.
Can I record live vocals and instruments with low latency?
Yes. Spider's Web Audio API engine supports sub-10ms round-trip latency for vocals, guitars and MIDI-controller performance through your audio interface. Your device, audio drivers and selected buffer determine the latency of your setup.
Can two people record audio into the same project from different locations?
Yes. Multiple users can work in the same cloud project. One producer can arrange drums while another records vocals or guitars on their own track. Session data syncs into the shared project; audio monitoring, playback and hardware I/O remain local to each user.
Can I record audio and immediately sample it?
Yes. Map recorded audio or imported stems into Eightcross HD, Spider's 8-lane sampler, for slicing, pitching and pad triggering. You can also convert recorded melodies into editable MIDI with the built-in neural Audio-to-MIDI engine.
Can I change the scale of MIDI I have already recorded?
Yes. Choose a key and scale in the MIDI Clip Editor and use Apply to Scale to reshape existing notes. Continue editing their pitch, timing, length and velocity, or ask Spider AI to develop the phrase.
Can Spider AI design a sound with effects?
Yes. Preset AI works with actual synthesizer parameters, including modulation, wavetables and FM algorithms on the relevant instruments. Enable AI+ to include the Instrument FX chain. Save the resulting synth and Instrument FX settings together as a preset.
How do I export my finished music?
Export a WAV or MP3 mix, or selected tracks. Choose the full arrangement, current Part or loop range. WAV options include 16-bit, 24-bit and 32-bit float. You can also export a portable .snu project file to reopen the editable session.
What is an online DAW?
An online DAW is a digital audio workstation that runs in a web browser. Spider lets you sequence, record, edit MIDI and audio, arrange, mix and export inside its browser-based studio.
Can I make complete tracks in Spider Neural Ultra?
Yes. Studio Flow, Song Parts, Arrangement, detailed MIDI and audio editing, built-in instruments, effects, mixing and export stay connected in one production workflow.
Does this online DAW work on tablet and mobile?
Use the full DAW or compact touch view on phones and tablets. Phones open the full DAW by default. Use the view button in the header to switch between them. Native VST3 hosting requires the desktop Bridge.
Can we work on the same Spider project together?
Yes. Invite a friend, producer or student anywhere in the world into one shared project. Follow their live cursor and selections, and see musical edits as they work. Each participant keeps independent local playback and monitoring.
Can an online DAW use VST3 plugins?
Yes. Spider's optional desktop Bridge hosts your VST3 instruments and effects inside the project, with multiple instances on their own tracks and inserts. Spider's built-in instruments work without the Bridge.
