Live LoopsFor spontaneous composition.

Live Loops is a dynamic way to create and arrange music in real time. Kick off your composition by adding loops, samples, or your recorded performances into a grid of cells. Trigger different cells to play with your ideas without worrying about a timeline or arrangement. Once you find combinations that work well together you can create song sections, then move everything into the Tracks area to continue production and finish your song.

Remix FX

Bring DJ-style effects and transitions to an individual track or an entire mix with a collection of stutters, echoes, filters, and gating effects.

Logic Remote

Control features like Live Loops, Remix FX, and more from your iPad or iPhone using Multi-Touch gestures.

New

Step SequencerPure beat poetry.

Step Sequencer is inspired by classic drum machines and synthesizers. Using the Step Sequence editor, quickly build drum beats, bass lines, and melodic parts — and even automate your favorite plug-ins. Add sophisticated variations to your pattern with a wide range of creative playback behaviors. Use Note Repeat to create rolling steps, Chance to randomize step playback, and Tie Steps Together to create longer notes.

Logic RemoteTouch and flow.

Logic Remote lets you use your iPhone or iPad to control Logic Pro X on your Mac. Use Multi-Touch gestures to play software instruments, mix tracks, and control features like Live Loops and Remix FX from anywhere in the room. Swipe and tap to trigger cells in Live Loops. And tilt your iPhone or iPad up and down and use its gyroscope to manipulate filters and repeaters in Remix FX.

Multi-Touch mixing

Control your mix from wherever you are in the room — whether that’s next to your computer or on the couch — with Multi-Touch faders.

Pair and play

Use a variety of onscreen instruments, such as keyboards, guitars, and drum pads, to play any software instrument in Logic Pro X from your iPad or iPhone.

Sampler

We redesigned and improved our most popular plug-in — the EXS24 Sampler — and renamed it Sampler. The new single-window design makes it easier to create and edit sampler instruments while remaining backward compatible with all EXS24 files. An expanded synthesis section with sound-shaping controls brings more depth and dynamics to your instruments. The reimagined mapping editor adds powerful, time-saving features that speed the creation of complex instruments. Use the zone waveform editor to make precise edits to sample start/end, loop ranges, and crossfades. And save hours of tedious editing with new drag-and-drop hot zones.

New

Quick Sampler

Quick Sampler is a fast and easy way to work with a single sample. Drag and drop an audio file from the Finder, Voice Memos, or anywhere within Logic Pro X. Or record audio directly into Quick Sampler using a turntable, microphone, musical instrument, or even channel strips playing in Logic Pro X. In a few steps, you can transform an individual sample into a fully playable instrument. And with Slice Mode, you can split a single sample into multiple slices — perfect for chopping up vocals or breaking up and resequencing drum loops.

New

Drum Synth

This powerful but easy-to-use plug-in creates synthesized drum sounds. Choose from a diverse collection of drum models and shape their sound with up to eight simple controls. Drum Synth is also directly integrated into the bottom of the Drum Machine Designer interface — giving you a focused set of sound-shaping controls.

New

Drum Machine Designer

Redesigned to be more intuitive and integrated, Drum Machine Designer lets you effortlessly build electronic drum kits. Apply individual effects and plug-ins on each discrete drum pad to experiment with sound design and beat-making in new ways. You can also create a unique layered sound by assigning the same trigger note to two different pads. To help you quickly edit sounds, Quick Sampler and Drum Synth are directly integrated into the Drum Machine Designer interface.

DrummerCompose to the beat of a different percussionist.

Using Drummer is like hiring a session drummer or collaborating with a highly skilled beat programmer. Create organic-sounding acoustic drum tracks or electronic beats with the intelligent technology of Drummer. Choose from dozens of drummers who each play in a different musical genre, and direct their performances using simple controls.

Compositions and PerformancesYour studio is always in session.

Logic Pro X turns your Mac into a professional recording studio able to handle even the most demanding projects. Capture your compositions and performances — from tracking a live band to a solo software-instrument session — and flow them into your songs.

The ultimate way to record.

Seamless punch recording. Automatic take management. Support for pristine 24-bit/192kHz audio. Logic Pro X makes it all easy to do — and undo. You can create projects with up to 1000 stereo or surround audio tracks and up to 1000 software instrument tracks, and run hundreds of plug-ins. It’s all you need to complete any project.

Get the most out of MIDI.

Logic Pro X goes beyond the average sequencer with an advanced set of options that let you record, edit, and manipulate MIDI performances. Transform a loose performance into one that locks tight into the groove using region-based parameters for note velocity, timing, and dynamics. Or tighten up your MIDI performances while preserving musical details like flams or chord rolls with Smart Quantize.

Industry-leading tools

As your song develops, Logic Pro X helps organize all your ideas and select the best ones. Group related tracks, audition alternate versions, and consolidate multiple tracks. Lightning-fast click-and-drag comping helps you build your best performance from multiple takes.

Smart Tempo

Go off-script and stay on beat with Smart Tempo, a way to effortlessly mix and match music and beats without worrying about the original tempo. Record freely without a click track. And easily combine and edit MIDI and audio tracks — from vinyl samples to live instruments to multitrack audio stems — with constant or variable tempo.

Flex Time

Quickly manipulate the timing and tempo of your recording with Flex Time. Easily move the individual beats within a waveform to correct drum, vocal, guitar, or any other kind of track without slicing and moving regions.

Flex Pitch

Edit the level and pitch of individual notes quickly and easily with Flex Pitch. Roll over any note and all parameters are available for tweaking.

Track Alternatives

Create alternate versions of a track or multiple grouped tracks, and switch between them at any time to audition different options. Create, store, and select from different edits and arrangements of track regions to make it easier to experiment with various creative ideas.

Takes and Quick Swipe Comping

Click and drag to choose the best sections of each take to create a seamless comp, complete with transition-smoothing crossfades. Save multiple comps and switch among them to pick the one you like best.

Track Stacks

Consolidate multiple related tracks into a single track. Use a Summing Stack as a quick way to create submixes. Or create layered and split instruments.

Project Alternatives

Create as many alternate versions of a project as you’d like, each with its own name and settings but sharing the same assets — efficiently saving storage space. Load any version to make changes without compromising your original.

Track Groups and VCA Faders

Manage large mixes with Track Groups and VCA faders. Assign any selection of channels to a track group, then control the levels or other parameters of all tracks in the group from any single channel in the group.

Automation

Easily capture changes to any channel strip or plug-in parameter. Just enable automation, press Play, and make your changes.

Even more pro features in the mix.

Logic Pro X is packed with incredible tools and resources to enhance your creativity and workflow as you sharpen your craft — even if you’re a seasoned pro.

The Isabelle^[a]automated theorem prover is an interactive theorem prover, a higher order logic (HOL) theorem prover. It is an LCF-style theorem prover (written in Standard ML). It is thus based on small logical core (kernel) to increase the trustworthiness of proofs without requiring (yet supporting) explicit proof objects.

Features[edit]

Isabelle is generic: it provides a meta-logic (a weak type theory), which is used to encode object logics like first-order logic (FOL), higher-order logic (HOL) or Zermelo–Fraenkel set theory (ZFC). The most widely used object logic is Isabelle/HOL, although significant set theory developments were completed in Isabelle/ZF. Isabelle's main proof method is a higher-order version of resolution, based on higher-order unification.

Though interactive, Isabelle features efficient automatic reasoning tools, such as a term rewriting engine and a tableaux prover, various decision procedures, and, through the Sledgehammer proof-automation interface, external satisfiability modulo theories (SMT) solvers (including CVC4) and resolution-based automated theorem provers (ATPs), including E and SPASS (the Metis^[b] proof method reconstructs resolution proofs generated by these ATPs).^[2] It also features two model finders (counterexample generators): Nitpick^[3] and Nunchaku.^[4]

Isabelle features locales which are modules that structure large proofs. A locale fixes types, constants, and assumptions within a specified scope^[3] so that they do not have to be repeated for every lemma.

Isar ('intelligible semi-automated reasoning') is Isabelle's formal proof language. It is inspired by the Mizar system.^[3]

Isabelle has been used to formalize numerous theorems from mathematics and computer science, like Gödel's completeness theorem, Gödel's theorem about the consistency of the axiom of choice, the prime number theorem, correctness of security protocols, and properties of programming language semantics. Many of the formal proofs are maintained in the Archive of Formal Proofs, which contains (as of 2019) at least 500 articles with over 2 million lines of proof in total.^[5]

The Isabelle theorem prover is free software, released under the revised BSD license.

Isabelle was named by Lawrence Paulson after Gérard Huet's daughter.^[6]

Example proof[edit]

Isabelle allows proofs to be written in two different styles, the procedural and the declarative. Procedural proofs specify a series of tactics (theorem proving functions/procedures) to apply; while reflecting the procedure that a human mathematician might apply to proving a result, they are typically hard to read as they do not describe the outcome of these steps. Declarative proofs (supported by Isabelle's proof language, Isar), on the other hand, specify the actual mathematical operations to be performed, and are therefore more easily read and checked by humans.

The procedural style has been deprecated in recent versions of Isabelle.

For example, a declarative proof by contradiction in Isar that the square root of two is not rational can be written as follows.

Applications[edit]

Isabelle has been used to aid formal methods for the specification, development and verification of software and hardware systems.

Language Proof And Logic Answer Key

In 2009, the L4.verified project at NICTA produced the first formal proof of functional correctness of a general-purpose operating system kernel:^[7] the seL4 (secure embedded L4) microkernel. The proof is constructed and checked in Isabelle/HOL and comprises over 200,000 lines of proof script to verify 7,500 lines of C. The verification covers code, design, and implementation, and the main theorem states that the C code correctly implements the formal specification of the kernel. The proof uncovered 144 bugs in an early version of the C code of the seL4 kernel, and about 150 issues in each of design and specification.

The programming language Lightweight Java was proven type-sound in Isabelle.^[8]

Larry Paulson keeps a list of research projects that use Isabelle.

Alternatives[edit]

Several proof assistants provide similar functionality to Isabelle, including:

Coq, similar system written in OCaml
HOL, similar to Isabelle's HOL implementation
Lean, similar system written in C++
