Shruti-Laya is a Carnatic music practice companion. Three independent,
perfectly phase-locked voices — tanpura, mrudangam, and manjira — play
together against the tala grid you choose, for steady, musical
accompaniment any time.
TANPURA DRONE
• Choose your tonic (Sa) across a wide range and the supporting string —
pancham (Pa), madhyama (Ma), nishada (Ni), or upper Sa.
• Adjust pluck rate and volume.
MRUDANGAM
• Tala-driven stroke playback with adjustable tempo (40–150 BPM).
• Optional pattern variations for a more lifelike accompaniment.
MANJIRA
• Cymbal strokes on every beat, on claps, on sam, or off.
PICK YOUR TALA
• All seven Suladi Sapta Talas — Dhruva, Matya, Rupaka, Jhampa, Triputa,
Ata, Eka.
• Set jaati and gati/nadai — Tisra, Chatusra, Khanda, Misra, Sankeerna —
plus a kalai multiplier. (Adi tala = Triputa with Chatusra jaati.)
BUILT-IN TUNER (new)
• Tune your voice or instrument to your selected tonic.
• Live swara name and a sharp/flat cents bar, right in the display.
Practice-friendly: pause and resume from the lock screen and Control
Center, and the drone keeps playing when the screen sleeps. Works on
iPhone and iPad.
NOTE: The Tuner feature uses the microphone to detect the pitch of the user's
voice or instrument and show how it compares to the selected tonic. Tap
"Tuner" above the on-screen display to try it; the app requests microphone
permission on first use. No audio is recorded, stored, or transmitted.
Don’t buy this app. It is completely nonfunctional. It doesn’t open.
Developer Response
App has been completely rewritten and works well on many devices tested. Could you please download the new version?
- Double-speed strokes are now possible. StrokeSpec.matraOffset changed from Int to Double, so a stroke can land between two matras (e.g. 24.5). adiCadence's beats 7–8 now play at double density (8 strokes instead of 4) as a worked example.
- Cadence plays more often. The Mrudangam variation phrase length dropped from 8 avartanas to 2, so the cadence-into-sam now shows up every other avartana instead of every 8th. (Trade-off: the other two Adi variations — "Ornamented fingers" and "Ta dhin dhin na" — no longer get a turn, since the only non-base slot is now always claimed by the cadence.)
Rhythm count-in (new feature)
- Pressing Rhythm Play now always plays a 4-click count-in before the avartana starts — and always starts fresh at sam, never mid-cycle from wherever a quick pause/resume left off.
- The LCD (both the small always-on display and the full-screen Performance LCD) shows 4 dots during the count-in instead of a confusing "beat 1": one dot disappears per click, and a "GET READY" label appears in bright yellow.
- The count-in uses the non-clap tick sound, so it doesn't get confused with the actual clap on sam.
- Under the hood, several correctness passes: the dots now track the same audio clock the clicks are scheduled on (so they can never drift out of sync), and a stale-engine-anchor bug that occasionally made the avartana restart at a random beat after a stop/start is fixed.
