Make your modulations groove with your music. When your LFO rate matches your track's tempo, modulations rise and fall naturally with the beat. This creates tighter, more musical movement where the modulation enhances the rhythm instead of fighting it. Modsync calculates LFO frequencies in Hz instantly based on your BPM and note division. Just copy the values into your synth or plugin. FEATURES - Instant tempo-synced LFO calculations - 6 rhythmic divisions from whole notes to 1/32 - Straight, dotted, and triplet variations - One-tap copy to clipboard - Beautiful, minimalist interface - Haptic feedback - Works completely offline PRO TIP With iCloud Universal Clipboard enabled, tap any value on your iPhone and paste it directly into your synth or DAW on Mac. No typing required. Perfect for music producers, sound designers, and synth enthusiasts who want their modulations to feel musical, not random. Made with love by AKER.
