The JD-1: an Implementation of a Hybrid Keyboard/Sequencer Controller for Analog Synthesizers
نویسندگان
چکیده
This paper presents the JD-1, a digital controller for analog modular synthesizers. The JD-1 features a capacitive touchsensing keyboard that responds to continuous variations in finger contact, high-accuracy polyphonic control-voltage outputs, a built-in sequencer, and digital interfaces for connection to MIDI and OSC devices. Design goals include interoperability with a wide range of synthesizers, very highresolution pitch control, and intuitive control of the sequencer from the keyboard.

Design and Implementation of Discrete Time Observer Based Backstepping Controller for a 2DOF Servomechanism
The two degrees of freedom servomechanism has many applications, including in gimbaled seekers. These mechanisms require closed-loop control to perform properly. In this paper, an observer-based multi-input-multi-output hybrid controller is designed for a two-degree-of-freedom servomechanism. Since in the model presented in this paper, disturbances on the mechanism are considered, so an extende...
متن کاملMidiKinesis | MIDI controllers for (almost) any purpose
MidiKinesis is a Python package that maps MIDI control change events to user-de ned X events, with the purpose of controlling almost any graphical user interface using the buttons, dials, and sliders on a MIDI keyboard controller such as the Edirol PCR30. Key ingredients are Python modules providing access to the ALSA sequencer as well as the XTest standard extension.

متن کاملLabVIEW implementation of an enhanced nonlinear PID controller based on harmony search for one-stage servomechanism system
This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...
متن کاملA class of multi-agent discrete hybrid non linearizable systems: Optimal controller design based on quasi-Newton algorithm for a class of sign-undefinite hessian cost functions
In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system. A...
