rezonateur's Issues

Réponse en fréquence

Un paramétrage qui permet de modéliser grossièrement la réponse fréquentielle de la bande passe-bas, en utilisant les filtres "à variable d'état" SVF.
Réalisé avec le logiciel tests/run-svf du dépôt. @jujudusud

Support for HiDPI screens

Can support for scaling/HiDPI screens be added. My screen is 3840 x 2400 and the controls on the plugin are barely legible.
